Description

Workshop Homepage

This workshop will examine the current state of knowledge of tau neutrinos and their role in understanding the lepton and neutrino sector of particle physics. We will examine the full range of tau neutrinos from GeV neutrinos produced in neutrino oscillations in accelerator experiments and the atmosphere to EeV tau neutrinos produced by astrophysical sources. The workshop will also examine future opportunities both in terms of ambitious experiments and expanded understanding of neutrino physics to use tau neutrinos as probes of new physics and precision tests of neutrino mixing, unitarity and other topics.

The below schedule is the current estimate of the program, subject to minor modifications.

A whitepaper will be produced summarizing the results of the workshop that will be used as input to the Snowmass 2021 community planning effort currently underway in particle physics. This whitepaper and the outcome of the workshop will help guide DOE HEP and the HEPAP and P5 (Particle Physics Prioritization Panel) panels to inform potential new research directions over the coming decades.

        Experimental overview: artificial sources 30m

        Artificial neutrino sources are complimentary to natural sources and in many cases have the unique capability that their characteristics can be optimized to specific physics goals. Identifying tau neutrinos from artificial sources is challenging, but has been done successfully by the DoNUT and OPERA experiments. Several experiments using accelerator-based sources of tau neutrinos that are planned or proposed for construction over the next decade. These include for DUNE, FASERnu, SND@LHC, and SHiP. This talk will summarize the status and prospects of these artificial tau neutrino sources.
