Satellite Workshop on multi-experiment oscillation measurements

The workshop will take place on Sunday, September 15 from 10:00 am to 5:00 pm. Please indicate your interest in attending the workshop during the registration. 

The workshop is in Building 362, room F-108.  This is a different building than the main Nufact workshop.

If you need to contact one of the local organizing group on the day of the meeting, contact Aleena Rafique at 785-317-6462 <aleena@anl.gov> or Maury Goodman at 630-303-3950 <maury.goodman@anl.gov>.

The current generation of long-baseline experiments has significantly advanced our knowledge of neutrino oscillations within the PMNS paradigm and in particular demonstrated that searching for CP violation in the lepton sector is feasible.  As these experiments have matured work has started to extract as much information from their data as possible, through both increasingly complex analysis but also through combined analysis of multiple experiments’ data.  Multi-experiment analysis provides three major benefits compared to the individual experimental measurements:

  • Increased statistics
  • Different systematic effects
  • Breaking degeneracy between oscillation effects, such as mass ordering and the CP phase

Two multi-experiment analyses have been presented publicly, combining the results of the T2K and Super-K collaborations and the T2K and NOvA collaborations, and this work is expected to continue while the collaborations involved collect more data.  Alongside this, the next generation of long-baseline oscillation experiments is under construction.  These experiments will provide an order of magnitude increase in event rates, allowing precise measurement of neutrino oscillations and an opportunity to test the PMNS paradigm.  To succeed in this, it is necessary to analyse data from multiple experiments in a coherent framework.

The primary goal of this workshop is to start a discussion in the community on how we approach this problem.  This will draw from the recent experiences with the T2K + NOvA and T2K + SK joint analyses and the successful work between ATLAS and CMS to learn what does (and does not) work when preparing for multi-experiment analyses.  The workshop also aims to engage the wider neutrino community, including reactor neutrino and atmospheric neutrino experiments, to understand how their data can be best used in these analyses.
