​​​​​​​​​Purpose:

Evaluate and demonstrate the experimental sensitivity of DUNE to various nucleon decay modes and other baryon number non-conserving processes.

​As of September 2017, the Nucleon Decay, Atmospheric Neutrino and Cosmogenic Working Groups have been merged into a single working group, the High-Energy Non-Accelerator and Nucleon Decay Working Group.​


Convenors:​Greg Pawloski, Vitaly Kudryavtsev​, Lisa Whitehead Koerner
