Hunting sub-GeV dark matter with the NOνA near detector

摘要

We study the sensitivity of the NO ν A near detector to MeV-GeV dark matter while operating symbiotically with the neutrino program. We find that NO ν A could explore a large new region of parameter space over the next few years for dark matter masses below 100?MeV, reaching the thermal target for a scalar dark matter particle for some masses. This result represents a significant improvement over existing probes such as BABAR , E137, MiniBooNE, and LSND.
