The transverse momentum distribution of the Higgs at large $P_T$ is complicated by its dependence on three important energy scales: $P_T$, the top quark mass $m_t$, and the Higgs mass $m_H$. A strategy for simplifying the calculation of the cross section at large $P_T$ is to calculate only the leading terms in its expansion in $m_t^2/P_T^2$ and/or $m_H^2/P_T^2$. The expansion of the cross...

When an excess appears in LHC data, we should compare the results with broad classes of models, to get an immediate sense of which kinds of BSM theories could conceivably be relevant. Often, the new physics is likely to be an s-channel resonance. In this case, a simplified model of the resonance can translate an estimated signal cross section into bounds on the product of the dominant...

Muon-based accelerators have the potential to enable facilities at both the Intensity and the Energy Frontiers, with industrial applications as well. Progress in muon accelerator designs has advanced steadily in recent years. In regard to 6D muon cooling, detailed and realistic designs now exist that provide more than 5 order-of-magnitude emittance reduction, with recent progress in...

We present the status of an ongoing lattice-QCD calculation of form factors for exclusive semileptonic decays of $B$ mesons with both charged currents ($B\to\pi\ell\nu$, $B_s\to K\ell\nu$) and neutral currents ($B\to\pi\ell^+\ell^-$, $B\to K\ell^+\ell^-$). The results are important for constraining or revealing physics beyond the Standard Model. This work uses MILC's (2+1+1)-flavor ensembles,...

A number of short baseline neutrino oscillation experiments have observed an anomalous excess of neutrinos in the low energy range. This may hint towards the existence of additional neutrino mass splittings. Therefore, additional sterile (non-interacting) neutrino states above the current 3 neutrino model would be required. On the other hand, many parameters of the allowed space are limited by...

Results are presented from searches for massive boson resonances with decay modes $X\to$ $Z\gamma$ and $X^{\pm}\to$ $W^{\pm}\gamma$ using 13 TeV proton-proton collision data collected by the ATLAS detector at the LHC in 2015 and 2016. For the $Z\gamma$ channel, a high $E_T$ lepton trigger selects events where the Z boson is detected from decays to $e^+e^-$ and $\mu^+\mu^-$. These data are...

The Bayesian Block algorithm, originally developed for applications in astronomy, can be used to improve the binning of histograms in high energy physics. Along with visual improvements, the histogram produced from this algorithm is a non-parametric density estimate, providing a description of background distributions that do not suffer from the arbitrariness of ad-hoc analytical functions....

We will present a search for dark matter in events with one or more jets and large missing transverse energy using proton-proton collisions at center-of-mass energy of 13 TeV. The data was collected in 2016 by the CMS detector at the LHC correspond to an integrated luminosity of 35.9 fb-1. The results are interpreted in terms of well known LED ADD model and new models, Fermion Portal and...

A charged Higgs boson is predicted by many beyond the Standard Model theories. Among those, the two-Higgs-doublet model (2HDM) extends the standard model with two Higgs doublets. Especially type II model of 2HDM predicts five Higgs bosons, negative/positive charged Higgs pair and three neutral bosons including light and heavy scalar Higgs bosons, and a pseudoscalar Higgs boson. In this talk we...

We present results of a new analysis campaign, which combines the final data samples collected by the B factory experiments BaBar and Belle in single physics analyses to achieve a unique sensitivity in time-dependent CP violation measurements. The data samples contain (471 +- 3) x 10^6 BB pairs recorded by the BaBar detector and (772 +- 11) x 10^6 BB pairs recorded by the Belle detector in...

Electroweak scale right-handed neutrinos have become a commodity in recent years. Most scenarios involve the so-called sterile neutrino paradigm, where right-handed neutrinos are assumed to be completely neutral under the Standard Model gauge group. A more interesting possibility is - of course - one in which they do interact. Such a fertile (non-sterile) possibility is certainly important...

The Long Baseline Neutrino Facility (LBNF) will use high energy protons impinging on a graphite target to produce kaons and pions, which will be focused by a set of magnetized focusing horns and directed into a decay pipe where they will decay, producing an intense neutrino beam. The neutrino energy spectrum can be tuned by changing a variety of parameters in the beamline such as horn and...

ANITA is a NASA balloon-borne radio (200-1200 MHz) telescope with a primary goal of detecting coherent radio emission from ultra-high-energy (UHE) neutrinos. The fourth flight of ANITA recently flew over Antarctica from Dec 2, 2016 through Dec 29, 2016. The best limit to date on the flux of the highest energy (10^19.5 eV and above) neutrinos comes from previous flights of the ANITA...

New physics has traditionally be sought in the high transverse momentum region at high-energy collider experiments. We show that, if the new physics is light and weakly-coupled, the very forward region also provides a promising location for new particle searches. Given an integrated luminosity of 300 fb$^{-1}$, $10^{16}$ light mesons are produced at ATLAS and CMS within 1 mrad of the beamline,...

A new solution to the strong CP problem with distinct experimental signatures at the LHC is proposed. It is based on the Yukawa interactions between mirror quarks, Standard Model (SM) quarks and Higgs singlets. (Mirror quarks and leptons which include non-sterile right-handed neutrinos whose Majorana masses are proportional to the electroweak scale, form the basis of the EW-$\nu_R$ model.) The...

LHCb has been collecting the world's largest sample of beauty hadrons available to date. This sample has been used to measure different sources of CP violation and search for beyond-the-standard-model physics. We present a selection of measurements performed by LHCb using the full Run 1 dataset and in some cases part of the Run-2 dataset, notably including: the measurements of the semileptonic...

NuPRISM is a proposed 1 kton water Cherenkov detector in the J-PARC neutrino beam, placed at a distance of around 1 km from the neutrino production point. The detector configuration allows for vertical movement over around 50 meters resulting in a wide span of angles with respect to the beam direction. Data taken at different off-axis angles is sampled from neutrino fluxes peaking at different...

At present most experiments at the CERN Large Hadron Collider (LHC) are planning upgrades in the next 5-10 years for their innermost tracking layers as well as luminosity monitors to be able to take data as the luminosity increases and CERN moves toward the High Luminosity-LHC (HL-LHC). These upgrades will most likely require more radiation tolerant technologies than exist today. As a result...

Neutrinoless double-beta decay, if observed, would signal physics beyond the
Standard Model (BSM). In particular, neutrinoless double-beta decay offers the possibility to test BSM theories that predict that neutrinos are Majorana fermions and that the lepton number conservation is violated. We investigate the contribution of possible extensions to the Standard Model Lagrangian that could...
