Dark Sectors with Coherent CAPTAIN-Mills

CCM is a liquid argon detector operated at the stopped-pion source at Los Alamos National Laboratory, built to detect neutrinos, dark matter, axion-like particles, and anything else that couples to photons or mesons. The experiment recently completed its run; I coordinate its analysis effort as we work through the full dataset. Critically, CCM will measure the electron neutrino charged current cross section on Argon at the 10’s of MeV scale, which is critical for DUNE supernova observations.
