Author: Doojin Kim
I will discuss the detection of sub-GeV-range cosmogenic signals at large-volume neutrino detectors such as DUNE, SK/HY, and JUNO, utilizing nuclear inelastic scattering channels featuring nuclear deexcitation gamma-ray lines. I will first briefly discuss the detection of neutrino signals and point out the potential of observing the 13-MeV oxygen line at SK. I will then propose a new approach to search for light dark matter (DM) in the range of keV-GeV in the context of cosmic-ray boosted dark matter. I will show that using a hadrophilic dark-gauge-boson-portal model as a benchmark, the nuclear inelastic channels generally provide better sensitivity than the elastic scattering for a large region of light DM parameter space.
