Disentangling sub-GeV dark matter from the diffuse supernova neutrino background using Hyper-Kamiokande
The upcoming Hyper-Kamiokande (HyperK) experiment is expected to detect the Diffuse Supernova Neutrino 3 Piece Outdoor Chat Set Background (DSNB).This requires to ponder all possible sources of background.Sub-GeV dark matter (DM) which annihilates into neutrinos is a potential background that has not been considered so far.We simulate DSNB and DM s
