Description

We discuss indirect searches for sub-GeV dark matter (DM) that annihilates directly to a neutrino pair or a pair of new bosons subsequently decaying to neutrinos. The neutrino spectrum from the DM annihilation is monochromatic in the former process and a polynomial shape in the latter case. As a benchmark scenario, we consider a gauged U(1)${}_{L_{\mu }-L_{\tau }}$ model under which a DM field is charged, and evaluate the sensitivity at the Super-Kamiokande and future Hyper-Kamiokande experiments. We also discuss the interplay between the muon g-2 anomaly and DM physics.
