Alessandro Tricoli: and also the wiki pages of the values of topical groups in the Community and agendas and also, we have a calendar, so you can automatically be updated.
Alessandro Tricoli: Of all the meetings that take place on a weekly basis, and also, if you want more information, how to be in touch my mailing list or slack channels there's a communication link down there.
Alessandro Tricoli: And also, we have high level and bi directional communication with other from case it's very important.
Alessandro Tricoli: To make sure we have good.
Alessandro Tricoli: communication with other frontiers and also was that important preparation this workshop So you see all the other frontiers here listed as one or two.
Alessandro Tricoli: years on, but also a marriage very quickly in our snowmass activity, the renewed interest for immune calendar, so we established together with accelerate different year.
Alessandro Tricoli: And the theory frontier, I mean collider form So you see here the convenience which belong to entry frontier actually the frontier, and also the theory frontier, and here we have a wiki page, which is newly created.
Alessandro Tricoli: So please join activities if you're interested in me and collider.
Alessandro Tricoli: Studies.
Alessandro Tricoli: And the snowmass thrives on the participation of early career physicist and snow massively the ideal environment for a young physicists to get involved promoter their work and think ahead because.
Alessandro Tricoli: This is the future of their career.
Alessandro Tricoli: And visit Korea representation in the energy frontier this rotates every three months and, at the moment grace cummings and that's the blonde are the representatives of the electorate.
Alessandro Tricoli: So if you are in Korea stage, please do not be shy get in touch with grace and matt if you, especially if you need guidance, how to effectively get involved in.
Alessandro Tricoli: Energy frontier studies release and that will help build British bridges between projects and you collaborators, so please get in touch and also yeah there are some links and points of entry for the courier people within their snowmass.
Alessandro Tricoli: And snowmass is really our time to innovate SF new directions, without barriers constraints said by our collaborations we want to explore the TV and the key skill and beyond.
Alessandro Tricoli: Trying to understand what should be in an escalator leptin leptin and how to harden let them harder and to do that we need to set some focus questions and focusing on open questions to evaluate existing ideas how those.
Alessandro Tricoli: Existing ids can help us as stepping stones towards.
Alessandro Tricoli: Addressing your questions, for example, if i'm not able to see results how that can be useful to ship studies for future providers.
Alessandro Tricoli: And also, this is important to identify new ideas sm engine and, ultimately, we want to study the marriage of a different color options.
Alessandro Tricoli: And this in the context, on your energy frontier but, together with other volunteers so bit of history, we had the kickoff meeting last May, and then we had the workshop and of the energy frontier in July, and we are the bigger the panel, where we asked some big picture question to.
Alessandro Tricoli: distinguish physicists and the zoom recording is available as link.
Alessandro Tricoli: And the scenario is changing very fast since last the since the beginning of snowmass or in just a year.
Alessandro Tricoli: We probably have evidence so we're breaking up some more the paradigm in the Latin flavor sector, so it becomes even more urgent now.
Alessandro Tricoli: To see how we can prob directly or indirectly in energy frontier the underlying flavor structure of the standard model So you see here to teasers to plots from.
Alessandro Tricoli: Latin flavor salty violation hgtv and the data theory discrepancy in do you manage to experiments I don't get into the details, this is a subject of the talk in the afternoon session.
Alessandro Tricoli: But this listen other point which is important these results visa.
Alessandro Tricoli: Possible evidence of breaking of the standard model program are coming at the moment from other frontiers repurchases or possibly illogical cosmological frontiers.
Alessandro Tricoli: However, the energy frontier, even though it may seem slower start, if necessary, to win the race to discover new fundamental laws of physics and the collider, which is very broad, we need to test many.
Alessandro Tricoli: syllables lily to pin down the origin of a new physics and there's a new complementarity between electronic procedural fits fits and flavor of syllables so please join the energy front to help us and win this race to understand the fundamental laws of physics.
Alessandro Tricoli: And we can do that with many possible machines that debate is of course between hydrogen colliders leptin colliders circular versus Alina colliders and don't have their pros and cons of many ideas, how to collide this of course allow us to reach high energy scales.
Alessandro Tricoli: can allow many multiple detectors perfected by poor signal to the ground ratio and by a PDF 70s, whereas, let me call either is much more clear environments large signal to the ground ratio allow color arise beams.
Alessandro Tricoli: That are limited in the mass reach supercolliders allow higher velocity several interaction points but affected by synchrotron radiation.
Alessandro Tricoli: Nikolai there is are easily upgradeable easier to implement polonaise beams but I love typically one single interaction point and affected by being strong, so this is a debate we are in.
Alessandro Tricoli: and towards the goal of trying to report we said some benchmark parameters for the various accelerated options which are the main one said.
Alessandro Tricoli: But this does not exclude that we should go beyond those parameters people have time to explore other parameters basis, so you see here for a bias adoptions, the central mass energy that we suggest to study the position of the beams the integrity luminosity.
Alessandro Tricoli: and moving towards more the organization apart, we are very happy that we receive a lot of interest from national, international community, we received this 76 letters of intent.
Alessandro Tricoli: Last fall or which to under 68 pertained it energy frontier alone, and many others are, together with other volunteers, and this was a major effort.
Alessandro Tricoli: or solicitation of allies from public group computers and and we are very happy that community is very much engaged, however, if you haven't submitted the Li no worries you're still in time just let us know your ideas your plans and a very much welcome to join our effort.
Alessandro Tricoli: I briefly on the timeline going forward so between January and June this year, we had to slow down or activities at the end of June we restarted our activities mid July, we had the dpf meeting with a snowmass town hall, and now we have this entry frontier restart watch.
Alessandro Tricoli: On the 24th of September will let us know nice day i'll get more details and it's around.
Alessandro Tricoli: Mid March is a deadline for contributor papers for submission a contributor papers.
Alessandro Tricoli: And domain is that line for the submission of cleary couple of group reports end of June is on the line for plenary frontier reports, this will lead to the.
Alessandro Tricoli: Mid July Community summit study in Seattle and eventually end of September will ever find reports that will lead to a publication of some ass book and archival documents and of October.
Alessandro Tricoli: The more details on the upcoming plans for the energy frontier.
Alessandro Tricoli: As I mentioned this snowmass day for all frontiers on September 24 and the frontier we give a short presentation, together with other frontiers, but will also have a terrorist procession.
Alessandro Tricoli: And the speakers will be illiterate people most likely postdocs, and so they give their perspective to topical group activities and provide highlights of liquor he studies.
Alessandro Tricoli: And then moving forward in winter will have probably fewer one day virtual workshops split by topic for example standard model hicks bsm etc to check the progress towards the master that line of code to the papers and discuss overlap with other.
Alessandro Tricoli: In spring will have most likely and, yes, why what's your review contributor papers towards the made it deadline for public group reports.
Alessandro Tricoli: And converge on summary plots and the main messages they want to get across.
Alessandro Tricoli: And between March and July will have simulations are preliminary reports, both at the group level, as well as energy from tier level will have public readings to collect the feedback from the whole community from all of you and improve our reports.
Alessandro Tricoli: and with this I can put just showing the agenda of the workshop here in blue you see the plenary sessions.
Alessandro Tricoli: We have run right one, right now, we have one in the afternoon after the break we'll discuss physics anomalies as a regular dissipated.
Alessandro Tricoli: and progress instrumentation tomorrow with our for two sessions, one on theory needs our feedback to two theories and progress and accelerators.
Alessandro Tricoli: And one on emerging future collider ideas and progress in this message, and then on Fridays will ever three hours, where we go through the highlights of topical groups highlights offer.
Alessandro Tricoli: A partner sessions, but also plans and we forward from the top level of convenience in green our partner sessions arranged by topical groups.
Alessandro Tricoli: but also our range, together with other 20 years One example is tomorrow afternoon, a session on.
Alessandro Tricoli: dark matter and the other one on the computational frontier, together with competition or frontier, and he are important, we have several unstructured discussion sessions.
Alessandro Tricoli: And the idea is to have most of the discussion brainstorming exchanging of ideas with Bailey for presentations the first one today with with Ruby with them.
Alessandro Tricoli: Community engagement frontier will discuss the funding issues in the energy frontier, which is becoming more and more pressing and how we can better reach out for government.
Alessandro Tricoli: And we have a three unstructured sessions Tuesday, Wednesday, Thursday Thursday with them accelerate different here, and very importantly, the last one.
Alessandro Tricoli: On Friday afternoon to discuss plans towards the final reports, how to present results, for example, plots and tables, so the agenda is really structured to facilitate discussion, so please participate, the discussion and hopefully won't be enlightening.
Alessandro Tricoli: And I don't need to go much into summary just very briefly, we have a very ambitious plan in the energy frontier, and we can accomplish this plans only if you helped us to do so.
Alessandro Tricoli: Within the industry frontier but also across other antivirus.
Alessandro Tricoli: We have restarted our activities which took off already last year, but we started full steam now where a lot of enthusiasm we hope this enthusiasm is renewed and now the plans and the structure organization continues as from last year, so please get involved, and hopefully you enjoyed.
Alessandro Tricoli: The workshop this week, thank you.
Meenakshi Narain: Thank you Alice Andrew out so if you have any questions or comments, please raise your hand will call upon you.
Meenakshi Narain: Okay, I don't see any hands raised in zoom so.
Meenakshi Narain: So the next Thank you Sandra for a very nice summary of the schedule and fans and so next i'm going to invite Laura arena to give the highlights of.
Meenakshi Narain: From the energy frontier work which has happened, mostly in during the slow down.
Meenakshi Narain: and pass, so please begin Nora.
Meenakshi Narain: Nora we don't hear hear you speaking.
Laura Reina: Sorry, I was muted, can you see my screen.
Meenakshi Narain: Yes, we see your screen.
Here, thank you, thank you.
Laura Reina: So, moving on to the highlights from the energy frontier, this will be structured as a highlights from.
Laura Reina: The topical groups that after a brief introduction that been the the soul and the backbone of the energy frontier and accomplished an enormous amount of work.
Laura Reina: Since they started being active in spring 2020 will say so to that the by the fall Community meeting that we had in October 2020 they had already outlined a very rich program of.
Laura Reina: physics so organized around the some key questions so that has been our modus operandi, from the very beginning.
Laura Reina: That I will use this introduction to their highlights in this very short presentation during the pause the topical groups groups have been there.
Laura Reina: They have not been as active as they used to be during the first part of us no mass, but they are served as a sort of reference.
Laura Reina: And minimal framework or two, which are all participants in the Community could refer to people could continue contributing or start contributing and then now back.
Laura Reina: eager to present what their physics plan is based on the work done in the past and more the contributions that that they have received so far, and you can also to recruit a new people to help with the work and bring in new ideas.
Laura Reina: So.
Laura Reina: As you have heard from Alessandro we have organized our work around the three main areas of send them more than a two week notice drug interactions and beyond the standard model and from the very beginning, we like the to propose it as as a goal to.
Laura Reina: bring out the fundamental questions so, to which we would like to find answer and, both in terms of theoretical investigation and experiments on investigations.
Laura Reina: So in the lead to week interaction area, of course, and beyond the standard model of physics, that the key question that came out there was really.
Laura Reina: Around the origin of the two weeks scale finding the origin of the scale and these materialized in many different studies from precision and the higgs measurements to constrain to valid physics that then give direct input to globally, the two week pizza.
Laura Reina: exploring the origin of the next potential through a measurement of the heat set couplings the connection between peaks and flavor as well as the.
Laura Reina: impact and and implications of naturalness this has been a focus points of that has been developed in many focus points are for both the literal Rican psm topical groups.
Laura Reina: bsm has then evolved along those two main track, so one more modern dependent and the other more modern specific or vice versa, if you want.
Laura Reina: And they're both complimentary to each other, both are very region and interconnected in ideas so models, as we know, they have they play a special roles.
Laura Reina: To link high level theoretical ideas to specific phenomenon in a very consistent way.
Laura Reina: But then the question is what the model should we consider which models so should we consider and how to compare model and model parameters basis in a consistent way.
Laura Reina: And are we leaving something out or they are alternative party that we need to to consider and that that's the point and that's exactly the place or a more modern, independent and agnostic way of addressing the problem.
Laura Reina: kicks in and becomes a fundamental becomes really important in particularly in avoiding gaps in coverage and in exploring ideas or characteristics that sometimes that can be hidden in the specificity of a given model.
Laura Reina: Now, if we wanted to talk about a future colliders both in the short term and in the long term, and we see that big portion of them is indeed hadron collider so clearly.
Laura Reina: The study of the nature of strong interactions in different regimes that becomes really important.
Laura Reina: And this has been the focus of the QC groups where the big question, the key question around which of the work.
Laura Reina: has nuclear that there's been a both at the fundamental level and then at the more applicant 11 or or or practical level, so they have gone.
Laura Reina: Over a broad range of question that that can we can summarize into addressing positivity.
Laura Reina: And negativity to see the effects, what do you aim for precision set and understanding the different levels and precision is definitely needed if we wanted to this machine.
Laura Reina: To use it to food is the potential of this machine at the percent level, which is what did they can they can reach this has been indeed the focus of the QC topical groups.
Laura Reina: That will be done reflected in the highlights that I will give shortly.
Laura Reina: So finding answer to these very general questions that we were able to outline as the foundation of our physics program within the energy frontier has brought the very interesting discussions.
Laura Reina: more specific discussion because the answers to these very general questions that bring specific questions.
Laura Reina: And they were both on the experimental side and on the theoretical side, of course, you want to ask yourself are.
Laura Reina: Given these plan which collider which detector properties are better tailor that to deliver what we wanted to achieve.
Laura Reina: I can we identify technologies that will represent the definitely step forward on the theoretical side, of course, the basic question, the most important question is just not.
Laura Reina: What do we need from theory So where is theory going to have the most impact, and how can we.
Laura Reina: strike the right balance of total freedom of of investigation and specific contribution to specific problems that can bring out to the potential of this machine even more.
Laura Reina: Both of these areas that will be the topic of several discussions and several parallel sessions, that we have set in place for these restart workshop.
Laura Reina: And we definitely need the contribution of everybody interested in contributing to push them forward and to be the learn from this discussion that's the next level.
Laura Reina: So come into the highlights from the topical groups, they are organized into three main areas, so a wiki CD and.
Laura Reina: Certain from the highlights from the last two weeks topical groups that are here represented in with a sort of a venn diagram approach.
Laura Reina: To illustrate about the specificity of each of them and the overlaps and then we have four four of them here for 123 and four, the first two are about his basic so within the Center model and beyond the standard model so couplings properties extended executors and their interplay.
Laura Reina: We have a little topical group or on heavy flavors so top about them charm and yeah for for were all electroweak physics comes together into formulating the best strategies for combine global pizza have a little precision observable six or.
Laura Reina: So to go to the highlights, or that they would like to present to you, I have to go very briefly over there are there are many more details in the slides that you are welcome to to read them.
Laura Reina: But we would we wanted to have these highlights thrown at you just have to somehow show as a preview of what is going to be discussed into the part of the sessions.
Laura Reina: And the instructor discussion, so that at the core of these words as a matter of fact, so yeah for one is the standard model pizza he suppose on properties and couplings.
Laura Reina: They had a series of a fantastic discussion during the preparation and the restart of these of our activities and.
Laura Reina: they're focused on the topic said that really are missing, so there are topics that, for which we really need a lot of investigation so light for me new power coupling so.
Laura Reina: The progress on the inverse progress problem, so how to investigate.
Laura Reina: The effect of new kicks hicks as a portal of new physics, will give us the information through investigation or specific extensions of the scale aspect of the standard model or through effective interaction where they participate.
Laura Reina: And we can go from a more general description in terms of effectiveness theories or two or more specific description in temple model send back.
Laura Reina: So utilizing both these directions and information on the parameters based on specific models from your team, the stations is extremely important.
Laura Reina: And of course the holy grail of the mall, which is the measurement of the hits the coupling as being one of their main focuses.
Laura Reina: Yes, what to is to be our standard model so a lot of interaction media, for one, of course, because a lot of the themes are the same.
Laura Reina: So investigating kicks in flavor investigating the surf cufflinks of the hicks according and beyond the effect of global pizza in.
Laura Reina: Limiting the possible extension of the skill set of the standard model, and how does that happen the different machines.
Laura Reina: has been part of the discussion, please slow down and has been maintained as background to new ideas and investigation that have been promoted.
Laura Reina: individually or together with year for one during the pause there and are now restarting full speed for the future series of meetings that they will.
Laura Reina: advertise during their parallel sessions, so that organized that, together with the other one with a three year for for.
Laura Reina: come into here for three top and heavy favorite physics, of course, the top physics, is an integral part of.
Laura Reina: Global pizza he has a lot of relevance for case studies as well it's everywhere, so we this group is intimately related to the study of the other religious groups.
Laura Reina: As well as the to the study of QC D E, F or five in particular.
Laura Reina: So prospect for precision measurements of top physics, are one of the highlights that they have developed a very rich program here.
Laura Reina: joy studies to determine precision so of with which we can determine fundamental parameter by the top NASA or.
Laura Reina: Effective coupling same way, to the top is involved, as we are, we will here in in the next session is a pair of the session dedicated to Robert fits in and eft.
Laura Reina: And, of course, the prospects for measuring.
Laura Reina: Other heavy flavors bottom and charm that are going a future colliders that are going to be fundamental to again both are investigating vs and physics and reaching precision, so it future machines.
Laura Reina: yeah for for is where everything comes together, as I said, they have been extremely active in.
Laura Reina: Putting this very difficult problem together, so the extension of global feats of the standard model to include effective interactions effectively theory interactions.
Laura Reina: They have now the task force in place and us for that has been super added by six members wanting to engage in more and more people are in these.
Laura Reina: Complicated studies that builder on water, the European strategy has brought us, but can have much more to that and brings us to something that is now under the attention of the global community, for instance, in conjunction with the similar efforts.
Laura Reina: Through the lsc eft working groups and.
Laura Reina: Moving on to highlights from the KC D topical groups 6456 and seven they explore aspects of both but typically have an opportunity to CD in different regions.
Laura Reina: Important to to the study of the year for fiber which is precision to see the are both aspects of both but to give an opportunity for specific CCD different that the precision of current.
Laura Reina: near future and far future hadron collider is at the percent level.
Laura Reina: They have been engaged in a variety of study on all these front from precision determination of a stronger input parameters, so the strong coupling constant.
Laura Reina: To the interface opportunity, because the calculation with Monte Carlo simulations, to the point of quantifying.
Laura Reina: The purity that fury can reach you taking into account know pretty pretty dynamic no activity that's effects, as well as studies.
Laura Reina: Of part and distribution functions in different regimes, together with the air for six or.
Laura Reina: QC if you want to see the strong interaction of just like jet so in different regimes and these in conjunction with the E, F, four, seven, as we were saying go button distribution functions are one of the highlights of the year for six so that is the group.
Laura Reina: specifically dedicated to to to CD for as far as pertains to hydroponic structure and forward to KC D.
Laura Reina: And to that they have added the two more highlights that is both of the analysis of the city, the study of ucsd in high density regimes.
Laura Reina: And that is becoming increasingly relevant if the arduino still see the SEC Asia and the urgency.
Laura Reina: And, as well as an activity that they have in common, now with the the real processes frontier, which is.
Laura Reina: The study of non positivity model of hundreds and hundreds spectroscopy they're organizing joint session so with.
Laura Reina: Many other with other topical groups, as well as with the process different tiers to which you're having invited if you wanted to join or participate or be updated on their physics plan.
Laura Reina: And finally, among the QC def or seven year for seven heavy volume so is a topical group that.
Laura Reina: leaves that the interface between particle physics and nuclear physics and because of that, and his mother said to leading to the very exciting time so of the I see.
Laura Reina: Because of that has that had to have a sort of a slightly different schedule with respect to the other groups so so it doesn't it didn't really leave the through the pause that that we have.
Laura Reina: Had for the past six months in this no man's Community exercise because of its own time framework that needs to also participate it to other Community exercises of planning processes.
Laura Reina: The one for nuclear physics, in particular, so they push forward during this time, and they have contributed the really important studies.
Laura Reina: at the interface with the particle physics colliders so basically the complementarity of a heavy hand studies, with the.
Laura Reina: Heavy sleeper studies jet studies, a little bit physics and even bsn studies as planned for future collider so in particle physics, they have dedicated their final session so enjoying sessions without a topical group at these meetings and.
Laura Reina: Everybody is interested in knowing about their studies and joining their studies and.
Laura Reina: Moving on to bsm topical groups, as I outlined at the beginning, the approaches being both thought to contribute to two studies in the literature, to see the section, but also to develop the two main leads one.
Laura Reina: oriented toward model specific explorations and the other towards a more general explorations and, as we all know in this context, all models are all general explorations our particular have a particular focus.
Laura Reina: On one question which is the question on dark matter about dark matter, the origin of the nature of that record and that's the reason for the existence of within.
Laura Reina: The energy frontier of a specific group but on dark matter colliders that has had a lot of overlap, so we both have Fo eight and therefore nine.
Laura Reina: As well as with other frontiers, in particular the cosmic frontier in by now has come up with a really stronger and important to highlight that will be will be briefly overview here so specific exploration, so of course.
Laura Reina: It involves going through.
Laura Reina: Several very promising and at the same time, are quite representative models and finding reasons to either explore them in conjunction or.
Laura Reina: single them out for specific physics pieces, they have had a huge activity during the pre pause the timer and capture that.
Laura Reina: Going good during the positive much slower pace, but enough to keep connection and cohesiveness among the people working at that.
Laura Reina: Before the the pause there they had to review that with dedicated meetings and partner activities.
Laura Reina: All the different scenarios that they wanted to explore in there now coming out after deposit with specific recommendations.
Laura Reina: They have planned for the multicultural needs, they will discuss in the months to come, finalized plots and tables as scenario said that they wanted to propose.
Laura Reina: For a future colliders investigations and the same time, of their activity is complemented and and in conjunction with the activity over here for nine, which is the more generic inspiration of bsm physics.
Laura Reina: With future colliders in mind and with the avoiding gaps in coverage, they have taken a different approach of.
Laura Reina: optimizing searches a future colliders in classes of particles that they they wanted to.
Laura Reina: explore and not miss that could be new heavy bows and sign a new firm user, as well as.
Laura Reina: Focusing on searches of particles that we haven't thought of so far with characteristic kinematic characteristics.
Laura Reina: or properties that that we haven't conceived so exotic searches or searches for assessor typically as a prototype example long leave the particles that will inform also specific.
Laura Reina: scenarios are both at the theoretical and experimental level.
Laura Reina: So.
Laura Reina: In this context, we, the year the work of year for 10 there has tried to talk to both of the.
Laura Reina: E, F topical groups, the eight and nine and the beyond the for the cosmic frontier.
Laura Reina: They have been very, very active before the polls that they have decided to use this low down period that you're connected to other activities in these very beach and very vital.
Laura Reina: scenario that he says listen honey of that matter searches and dark matter.
Laura Reina: dark matter physics community, so these meetings that will present results from activities activities on dark showers in conjunction with the F or nine.
Laura Reina: or a studies of a wimp set me on collider send me a letter that matter that hundred and after colliders they will present the results that that have been obtained, meanwhile, in particular by young representative of the Communities, which is very.
Laura Reina: What comes in particular to engage them more and more emphasis know myself or and they are recruiting more people interested in the topic.
Laura Reina: So we invite you to participate it to their sessions, so one last thing that we would like to advertise as one of the activities.
Laura Reina: not have a specific topical group about all the form that has been forming within the energy frontier during.
Laura Reina: As a matter of fact that pause in particular is the moon collider for this was a started, together with the other initiatives around the water that are summarized in a backup slides.
Laura Reina: and has been started, as I was saying, really, when the possible starting so in January 2021 so they haven't been any pause.
Laura Reina: But they had four meetings that you in this time in an upcoming one on September 21 which were all invited.
Laura Reina: They will have dedicated sessions during this workshop, as well as the instructor discussions.
Laura Reina: In which they will take time to both present the physics highlights, so how this machine response to the main to the main topic, the question presented in the introduction to these talks.
Laura Reina: As well as, of course, as a new technology highlights on accelerated and detectors to so please join the discussion.
Laura Reina: So I would like to conclude by reminding us that what has been the main spirit of the energy frontier, and what we have been wanting to stress and.
Laura Reina: around which we have informed these restart workshop is the synergy between topical group and without the frontier.
Laura Reina: As illustrated again in this plot where you see the overlap between the little weekend QC and bsm a part of the energy frontier topical groups.
Laura Reina: Is the connection with the other film last frontier from the computational to the accelerate instrumentation re processes that cosmic frontier neutrino frontier and, last but not least, that if you're referring to.
Laura Reina: And if we go back and have a look at the program our program you can see that really most of the spirit of this workshop as being.
Laura Reina: Cross breeding and talking to each other so starting from the plenary talks, some of which have been dedicated the two speakers.
Laura Reina: That are mainly active in other frontiers, like the right processes frontier they certification frontier the accelerator frontier will also have a plenary discussion with the theory frontier.
Laura Reina: And then the joy perilous session among topical groups and informed unstructured discussion now with other frontier the accelerator frontier the Community engagement frontier and the computation of frontier.
Laura Reina: One last unstructured discussion section which we would like to bring strongly your attention to is the last one, the one we're going to have on Friday, where we all come together.
Laura Reina: To really plan our reporter and to discuss how we want to present the results, so this will be a discussion of things that will be discussion of how we want those teams to make it to plots and tables, so please participate it to these joint discussion and session, Sir, and.
Laura Reina: bring your contribution, now and in the months to come to the success of the physics programmer of the energy Thank you.
Meenakshi Narain: Thank you Laura for a very extensive a quick summary of all the work which has been going on during the slow down.
Meenakshi Narain: Any questions or comments so Laura please raise your hand.
Meenakshi Narain: Okay, so there is one raised him from Sabina chrome Please go ahead.
Sabine Kraml: Yes, Hello.
Sabine Kraml: hi so i'm i'm wondering whether anybody in this forum is.
Sabine Kraml: is considering the day the Needle for analysis preservation and wings mean specifically but not exclusively, not only for for the hicks way so it's it's not so obvious to bring everything to bed in the Korean picture and actually I have a.
Sabine Kraml: global view of what order experimental data is telling us is already bringing a plus in cms results together it's not so easy and when when looking in the in a more distant future, incorporating maybe also is also Mara.
Sabine Kraml: experiment or colliders.
Sabine Kraml: The database that we saw some research is really, really important yeah.
Sabine Kraml: Well, known as is a long term it for two minutes anybody really considering this.
Laura Reina: yeah this is, this is a big problem, and this is an important one, and definitely need to be to be discussed.
Laura Reina: So, from the point of view of not of course losing memory, or what has been done a lot of the working groups, all of them, I would say started their their work from.
Laura Reina: Reviewing what the integration for the European strategy, but and building on that, but I think that your question was even farther, and that is really is really not losing track of of.
Laura Reina: Analysis and work that has been done within also the experimental community and and I think that we are all aware of that and.
Laura Reina: If it will be good also and I think during these meetings we have discussion planned to.
Laura Reina: Ensure that to ensure to try to to address this problem, but the more specific discussions.
Laura Reina: are welcome the requested that definitely snowmass, as you say, he is a place of where this discussion should happen.
Meenakshi Narain: Well, I think, in the sunroom to comment as well.
Alessandro Tricoli: yeah I just yes, Sir, thank you, I just want to point out that we have a session on Tuesday.
Alessandro Tricoli: session with a competition of frontier, which is shown there in green on Tuesday afternoon one to 230 I think that could be actually a good place to bring this up.
Alessandro Tricoli: Because those number can be additional but data preservation and as part of a data storage.
Alessandro Tricoli: And the formatting for for the future, so I think it's very important topic, and maybe that's a good place to bring this up, so I will keep that in mind and, hopefully, you can join the discussion, too.
Sabine Kraml: Yes, so make sure you're intending to do you have already been discussing the White Paper on norm for fuss no muss particular under musicians but it's very little discussed in the in the physics scopes.
Sabine Kraml: And that there has to be zones and more communication into my mind So yes, this is transition may be useful.
Alessandro Tricoli: Very good, yes let's get the list of things that you want to discuss in that session, thank you.
Laura Reina: Thank you.
Meenakshi Narain: Thank you and we'll move on to the Thank you Nora and move on to the next speaker, which is john stupak and he's going to give us a summary of the progress made for Monica productions and future plans and efforts, thank you.
Meenakshi Narain: Please go ahead john yeah we see your site.
John Stupak (he/him): Okay, thank you mean actually yeah so.
John Stupak (he/him): i'm going to try to keep this quick and to the point and give you the the status on production and background Monte Carlo samples, on behalf of several people whose whose names you'll see in a minute.
John Stupak (he/him): So Alejandro kind of went over this background already so I won't go into any detail i'll just say.
John Stupak (he/him): We have a wiki here, where you can go to find any information on related to the stuff i'm going to talk about today it's not super well populated at the moment but we're going to add more information to it.
John Stupak (he/him): And here's so so the backstory is that the Monte Carlo production Task Force came up with a plan for production of Monte Carlo samples that plan is now being carried out by the Energy frontier Monte Carlo production team who's consists of the folks you see here.
John Stupak (he/him): For a variety of completely understandable reasons, you know we've we've lost about half of these folks to attrition now, since we got started, you know, we had to pause we lost some momentum people have to you know things come up and they have to refocus their efforts so.
John Stupak (he/him): there's really just two people who are actively you know really have their hands on code and developing things and we really need some additional person power to help.
John Stupak (he/him): develop this workflow and validate the sample so I have a link here, if you have any spare time, please click this link.
John Stupak (he/him): And, and of course I do value everyone's contributions who's been contributing so far, whether they're actively contributing with their hands on code or whether they're you know, providing technical expertise and attending meetings everyone's efforts are very welcome.
John Stupak (he/him): These are the colliders and energies we we plan to support as a as a for the Community, we have you know the circular machines, the linear machines we've got the new on collider there.
John Stupak (he/him): eh we've got we want to try to support everything that the Community has an interest in so, so this is what the current plan is.
John Stupak (he/him): We plan to produce these hh samples that I had listed on that table proactively meaning you don't necessarily have to request them we're going to go ahead and produce them, no matter what, because we were pretty confident they're needed.
John Stupak (he/him): On the E H immune new samples though we're less certain about and and we're not so so we're not going to produce them unless.
John Stupak (he/him): Someone requests those samples so far we've gotten no request for any eh or Mumia samples, so if no one asks for it's not going to get produced if you need those samples.
John Stupak (he/him): that's fine just let us know at the at the link here and we'd be happy to help you but otherwise we're not going to do it if no one needs to.
John Stupak (he/him): The os JI has been very generous and it's helping us out a lot.
John Stupak (he/him): With this production they've offered they set up this really nice machine a dedicated machine just for snowmass called snowmass connected if you're if you've heard of cms connector or any of these.
John Stupak (he/him): osu connects then it's been it's relatively familiar to it's very similar to those it's an interactive login node batch submission and a lot of storage.
John Stupak (he/him): So this is a really nice machine we're going to use it to produce the the Monte Carlo that for everyone to use.
John Stupak (he/him): But this these resources can also be used by anyone for any snowmass use case the usg it would be very happy to see us using this and burning cpu cycles that they can report.
John Stupak (he/him): To their funding agencies so so they would be very happy for us to use this it's better than my local tier three I am I love using this machine I use it every chance I get.
John Stupak (he/him): If you don't have an account, yet you can request one here there's documentation here and we are using slack for user support and discussion, so please feel free to use these resources.
John Stupak (he/him): A few words on what we're not going to do we're not going to be producing any signal money, Carlo.
John Stupak (he/him): signal Monte Carlo is not really is specialized and it doesn't require a ton of resources, so we think people can generally handle signal Monte Carlo production on their own.
John Stupak (he/him): we're not going to touch that but, of course, you can use those osd resources to generate your signal Monte Carlo if you need to.
John Stupak (he/him): And we're also not going to produce any full seven samples, the reason for this is.
John Stupak (he/him): All of these future collider study groups are very happy to let people do studies, with their existing fulsome samples.
John Stupak (he/him): They just make very minor and completely reasonable in positions like, if you want to use their money, Carlo.
John Stupak (he/him): You should attend a meeting of there's every now and then and present your work, so that they get to scrutinize it to some degree, so if you if you want to do some study and you require the accuracy of four, seven, you should be talking to the future clutter study groups.
John Stupak (he/him): Unless they don't if they don't have something you need, then you can come talk to us and we can we can see about getting it produced.
John Stupak (he/him): But because using fulsome Monte Carlo from a foreign experiment is tricky and there's a bit of a learning curve, we did organize a series of Monte Carlo tutorials for each of these you know future colliders that you see here i'll see actually did a few.
John Stupak (he/him): tutorials one was sort of a general wizard tutorial and they did an analysis walkthrough but the other experiments have also done a nice tutorial So if you if you want to use any of this full Sam and you're a little confused about how to get started, these would be a good resource.
John Stupak (he/him): So what are we going to do we're going to produce a whole bunch of Monte Carlo with delphia fast simulation it's you know widely used well known fast and accurate enough for most snowmass studies.
John Stupak (he/him): And there are detector cards that have been blessed by all these future collider study groups already so we can just go ahead and use those blessed cards and generate the Monte Carlo so that's that's what the plan is.
John Stupak (he/him): On now since we're focused initially on hadron collider because that's where, as I said, that's where where we know we're definitely going to end up producing some money, Carlo so i'll go into some detail on the strategy there.
John Stupak (he/him): You know when you're talking about 100 TV collider the you know the Cross sections, for even what we consider rare processes like try bows on production, you know these these get these become large and.
John Stupak (he/him): We have to worry about a whole whole wide range of backgrounds and you know we're trying to anticipate you know all the different kinds of studies that people might want to do so, we have to be.
John Stupak (he/him): Really, inclusive and try to generate as many you know, Sam all backgrounds as possible and that requires some you know organization in order to keep things you know sensible and limit the number of samples were producing.
John Stupak (he/him): So we're following a similar strategy that we followed in 2013 and here's sort of the way we've categorized different standard model processes.
John Stupak (he/him): we've grouped them into you know groups of processes that have similar cross sections, so we can just generate one sample and we'll get you know, a sufficient number of events for all of the different.
John Stupak (he/him): processes that we've lumped together, so the be here, basically means a bose on photon wc and sometimes higgs depending on which sample we're talking about, but no suit, so we have both on diapers on try bows on.
John Stupak (he/him): An l here means a leptons so when you see ll that means off Shell di leptons llb is off shall die leptons placebos on higgs single top signal top placebos on Tiki bar and TT plus goes on.
John Stupak (he/him): And for each of these.
John Stupak (he/him): We veto the presence of on shall internal propagator is to keep all of these different groups of processes orthogonal to one another.
John Stupak (he/him): In 2013 what we did was we we took each of these samples that's listed here and we sliced it in hd and had you know so four to six slices and he for each of these samples, which obviously you know blew up the total number of samples and and you know.
John Stupak (he/him): This organization became a little bit trickier so we'd like to not have to do that, and so the plan is this time we would like to instead of slicing hd we want to use.
John Stupak (he/him): Something called a bias function that can bias, the generation of the matrix at the events matrix element Level two large hd and we think we can solve the problem that way and just have one sample per process group here.
John Stupak (he/him): And in 2013 what we did was we treated all the on shells residences as stable at matrix element level, and then we decayed them democratically using bridge and by democratically, I mean basically equal.
John Stupak (he/him): branching ratio to leptons and hadron so that we could populate you know those enhance our statistics and final states with lots of leptons.
John Stupak (he/him): Bridges kind of an old.
John Stupak (he/him): Product at this point and we want to move to something more modern, so we want to use mad spin to to replace that functionality.
John Stupak (he/him): And then so i'm talking about biasing things in terms of laptop multiplicity and in terms of hd.
John Stupak (he/him): So the way we, the way we did previously in the way we will again recover our physical distribution is via the use of an event wait, so there will be one event weight calculated in the file you'll have to apply that event weight and you'll require recover physical distributions.
John Stupak (he/him): So, again here's the proposed workflow that we wanted to use we wanted to use matt graph where we would generate up to four part cons that matrix element level.
John Stupak (he/him): So, in the case of Tiki bar, that would mean generating PP goes to T T or T T plus J or T T plus two jet's we would then use matt spin to perform a series of one to end the case of these heavy resonances.
John Stupak (he/him): So that takes our you know TT plus jj final state, all the way to you know, an eight part on final state.
John Stupak (he/him): So, by using that spin where we're really able to generate an eight part con final state in the amount of time it would typically take to generate basically a four part on final state so save us a lot of cpu.
John Stupak (he/him): And then we wanted to use pithy for showering and modernization and delphia selfies for detector simulation, as I mentioned.
John Stupak (he/him): This is our proposed workflow Now let me talk about some of the challenges and the status of.
Things.
John Stupak (he/him): So I mentioned, we want to do this ht bias here's here's a picture of what I was describing earlier, this is from 2013 where we had a you know, a sample in four different he slices.
John Stupak (he/him): That when you combine together gives you a nice smoothly falling at distribution.
John Stupak (he/him): This time, rather than slicing we want to bias, the generation in hd so what I what I did was I generated a di both on sample.
John Stupak (he/him): In black, with no bias and then in red and blue I bias, the sample to large ht or large H T squared in the case of blue so So you can see, we have.
John Stupak (he/him): And we have enhanced our statistics at high w PT in the red and blue, but then, when I apply the event wait that matt graph calculates red and blue turn into this Green and yellow distribution.
John Stupak (he/him): which if I zoom in you can see, does nicely match the black unbiased distribution, but we have far smaller error bars on the yellow and green Monte Carlo here than the black so we've we've.
John Stupak (he/him): decreased the statistical uncertainty out in the tales of this wpc distribution and here's the WHO distribution as well just to show that also you know Ada Ada gets corrected with this event wait.
John Stupak (he/him): So this is a bit of a work in progress, because it seems to be working here but, but we need more validation of this before we we feel it's really ready to deploy wide scale.
John Stupak (he/him): arm on mad spin.
John Stupak (he/him): If you're unfamiliar with Madeline What it does is it does a series of one to end the case and it's capable of preserving spinning correlation and finite with the facts.
John Stupak (he/him): That sounds great, but the devil is in the details, by default, mad spin can only do one to two the case so that means we can't, for example, to K higgs to for firm aeons.
In this default mode.
John Stupak (he/him): So what the authors did was a developed in another set another mode where specifically for decaying scales, like the higgs where it allows you to K to for firm aeons.
John Stupak (he/him): But unfortunately you can't combine these different modes of operation in a single job so either have to choose if we wanted to K tops w's and z's with their spin correlations or if we wanted to K, the higgs to for firm aeons but we can't do both within a single sample.
John Stupak (he/him): So the answer to that problem is fairly obvious you just generate samples with the higgs separately from from samples that have a top or a w or Z and then you can use, you know that the appropriate mode in both cases.
John Stupak (he/him): The only problem with that is what to do with samples, like the H or T Th where we have both you know particles that we wanted to K with spin correlations and the higgs which we wanted to cater for firm aeons.
John Stupak (he/him): there's a there's even another wrinkle that factors in here, because we also want to use mad spin to enhance our rare decays and i'm using the term rare here very loosely to even include w amp Z to case to leptons.
John Stupak (he/him): So i'm i'm working with Olivier metal yay from you know, one of the mad graph authors to develop this capability in mad spin.
John Stupak (he/him): his initial idea only work for wc and pop the case, but you can see it works really nicely these two plots here are both have left hand multiplicity on the Left it's it's raw Monte Carlo events.
John Stupak (he/him): And this red sample is what you get with you know this is Tiki bar, so this is the you know the the.
John Stupak (he/him): The raw laptop multiplicity distribution in in red and what I did artificially in green is artificially bias to high laptop multiplicity right we see this, the green distribution is shifted to the right.
John Stupak (he/him): But then when you apply the Monte Carlo event way that mad spin calculated.
John Stupak (he/him): You go from these distributions to these distributions and now my Green distribution perfectly matches the you know the the nominal district, the nominal more laptop multiplicity distribution.
John Stupak (he/him): So we had figured something out that worked for WCs and top decays but doesn't work for higgs is so Olivier now has a different strategy that we're trying to work out but August vacations cake got in the way of things and I need to need to come back to that.
John Stupak (he/him): But it's something we're working on.
Meenakshi Narain: john.
John Stupak (he/him): Oh sorry yeah um yeah.
John Stupak (he/him): So, so that so here's again the proposed workflow it was mad graph with an htc bias, followed by mad spin with a laptop multiplicity bias, followed by pithy and selfies.
John Stupak (he/him): In the interest of getting some samples produced in time for today, you know for this workshop, but we did was we prioritize a bit of a simpler workflow where we just replace this blob here with Cynthia.
John Stupak (he/him): So we're just gonna you know we're generating up to four part times up with matt graph within the King them with Pitsea so we have no spin correlations.
John Stupak (he/him): And then we're we're doing detector simulation with selfies but even this is not validated, yet we just I just you know we just put the finishing touches on some grid packs on Friday, and we have left the grid churn over the weekend to produce some money, Carlo for today.
frankjp: So these symbols are imperfect.
John Stupak (he/him): we're never going to be able to populate the tales of the distributions with this simple strategy, so we need to do better, but we need.
John Stupak (he/him): More person power to help us with that, so please if you're interested in getting involved with this please you know click the link here and volunteer or volunteer your students are postdoc.
John Stupak (he/him): So we're you know Andrews finish submitting and monitoring jobs over the weekend using hit this snowmass Monte Carlo framework that he developed we're running at 13 and 100 TV with the FCC hh delphia card at both of those energies.
John Stupak (he/him): The the out the data will very, very soon be available here it's just a temporary location, when we have to transfer it over to permanent home and we're working on easier web access for that.
John Stupak (he/him): But we have some you know some events here for these processes, all of the ones I mentioned, except for the you know the glue on fusion hig sample which, which is.
John Stupak (he/him): will be available soon, but we have something like eight terabytes of data that we produce this weekend and people can take a look at.
John Stupak (he/him): Again it's not validated so we're sort of crowdsourcing this and and we need help validating this So if you want to help validate you want to help develop new Monte Carlo techniques, whatever please click this link and let us know.
John Stupak (he/him): And then here's my summary that i'll just you know the three most important things are that we volunteers and if you need more info on anything I said here's a link to our wiki which should have the Info.
Meenakshi Narain: Thank you john for a very nice overview and great progress not Monte Carlo generation, so thank you very much to you and your team on this point i'd like to see if anyone has any questions or comments I see Michael.
Meenakshi Narain: Michael.
michael peskin: Oh yes, i'm.
michael peskin: So john didn't say anything about the policy minus resources, but I just like to say that the IOC team actually even last fall set up a web page with a great deal of simulation data at all of the relevant energies to.
michael peskin: And one TV, together with tutorials and some documentation and I think there are several groups that are using this now, who are new to the policy minus studies.
michael peskin: But I encourage other people who would like to do studies in the policy minus to visit this page all the standard model backgrounds are there, so you don't have to do that.
michael peskin: um it's this page is at the level of Dell focus, but let me just say that linear circular all these the policy minus machines are basically looking at the same physics there it is and so.
michael peskin: We really encourage you to use all the simulation data that's here a lot of interesting studies can be done.
michael peskin: If you have any questions about this, please feel free to write to me by email.
michael peskin: And I can get you connected to the right people if you want to do full simulation I can also get you connected to the people that can help you with that so um it's there, please use it, and hopefully we can do some interesting studies for singles.
John Stupak (he/him): Thank you for that reminder Michael yes, the irc was really fantastic and put together a great documentation, so it should be easy for people to jump in.
michael peskin: yeah i'll put the URL in the chat.
Meenakshi Narain: Thank you, gentlemen, Michael so next hand is raised is mark hungry he's.
Marc-Andre Pleier: around this is Marc Andre speaking, I have a question regarding the background where the kind of samples that are now you started running them.
Marc-Andre Pleier: Is there a way to access the card files, because, as you will see if you want people to generate the signal mother color samples.
Marc-Andre Pleier: They need to be able to access the background settings so they can make sure, things are generated consistently from the pdfs used to all the other nitty gritty details, I think it will be very good.
Marc-Andre Pleier: To have access to the card files and at least glancing through the tricky page I wasn't able to find them.
John Stupak (he/him): yeah so the wiki page I need to update, with all the latest stuff that's going on we've been focused on trying to get it produced first.
John Stupak (he/him): But if all that nitty gritty info is available at this link here at the bottom of this slide which shows you exactly how we're installing things and then there's you know the one the cards The the one non default card we're using right now is in that directory.
John Stupak (he/him): If anything's unclear, though.
John Stupak (he/him): Please let me know and i'll make sure to add that.
Marc-Andre Pleier: Thanks.
Meenakshi Narain: Thank you john mark Monday so next is from Jeff.
Jeff Shahinian: yeah hi thanks john for the talk and all the hard work from everybody in the MC Task Force is great to see my question was basically along the same lines is Marc Andre is about trying to.
Jeff Shahinian: coordinate different settings between people who are going to be generating signal Monte Carlo and and what the.
Jeff Shahinian: How the background samples will be produced so like maybe one thing that I guess hasn't been talked about is whether pileup is included in these background samples and then how.
Jeff Shahinian: People generating signal might include those and maybe to ask if it's possible that we could avoid sort of mismatch mismatches and delta's card.
Jeff Shahinian: parameter settings by I don't know sending the Monte Carlo task force a grid pack or something like that, and then they they handle the Delphi as part of the.
Jeff Shahinian: workflow.
John Stupak (he/him): yeah that is so that is something we've talked a little bit about inside the task force, we we want to make it super easy for people to generate signal, but so far we've been focused on getting the background stuff generated so.
John Stupak (he/him): We haven't quite figured out if we're gonna support you know people give us a grid pack, we then run it I don't see why we can't do that you know it's once you have the grid pack it's pretty easy to turn the crank and let it run.
John Stupak (he/him): But we will certainly make sure everything, everyone has the Info they need to you know produce equivalent signal Monte Carlo.
John Stupak (he/him): On the pile up question we're using we're using the official FCC H H card.
John Stupak (he/him): Which what this the approach they took was they do not explicitly overlay pile up events on the hard scatter events they have just parameters, the performance of their detector.
John Stupak (he/him): In the presence of pile up and then put fed that parameter ization into the card so we're implicitly, taking into account that the degradation of performance we're just not explicitly simulating a pile up.
John Stupak (he/him): So what people have to do is just use that exact same blessed FCC hh card with delphia and they should be fine.
Jeff Shahinian: Great yeah that helps clarify things for me thanks okay.
Meenakshi Narain: Thank you.
Meenakshi Narain: Oh.
Meenakshi Narain: I think the last question would be from CIRCA.
Sergo Jindariani: Thanks actually it's rather a comment just wanted to come in, in line with what's been previously said but regards to the new on collider I know that.
Sergo Jindariani: john has said they haven't been a lot of requests I know a fair amount, people are actually generating private samples, both in full Sim and outs.
Sergo Jindariani: But we do have.
Sergo Jindariani: You know, to links to the hands on tutorial we have material on how to generate those samples and also encourage people who are new and interested in.
Sergo Jindariani: Engaging in simulation to contact us Laura had our contact information on the slides I believe are the pointer to the wiki where you can find all the information so reach out to us and we'll be able to get you going with simulation or or you know help you to simulate samples unique.
John Stupak (he/him): yeah, just to clarify when I say we haven't gotten any requests I mean the Monte Carlo.
John Stupak (he/him): Production team that's completely separate from you know what the new on collider folks might be hearing from people interested in that or i'll see folks.
John Stupak (he/him): might be hearing from folks interested in the IOC so yeah and I drew a hard line here on Ian eh samples, but because me on colliders a bit in a unique position, and you know.
John Stupak (he/him): playing a bit of ketchup to the other ideas I didn't draw a hard line here i'm new on so you know if there's something that related to new on colliders that comes up in the future.
John Stupak (he/him): and
John Stupak (he/him): task for me, can help in any way, please let us know.
Meenakshi Narain: So, thank you very much john for the this.
Meenakshi Narain: detailed presentation and with this i'm going to close the first binary and we thank all the speakers for today's talk to Sandra and john.
Meenakshi Narain: And for Nice summary of the work going on in the last few months, during the slow down pause of the snowmass and.
Meenakshi Narain: The next session is going to be on discussion on global eft fit so for that session i'm going to hand it over to iris jumping and oberto to convene it i'm sorry we are running a bit late Thank you so i'm going to stop.
Meenakshi Narain: This recording and i'm going to do and iris.
Freitas, Ayres: is going to start start the at all.
