​​​​​​​​​​​​​​​​Purpose: ​

​Evaluate and optimize sensitivity to low-energy (up to ~100 MeV) neutrino physics in DUNE.  We are concerned mainly with supernova burst neutrino physics, but also will also be covering solar neutrinos and diffuse supernova neutrino background, which have issues in common.

​Coordinator/Manager/Convenor:Inés Gil Botella, Kate Scholberg, Alex Friedland​ (theory)
