Dark matter interpretation of the Super-Kamiokande antineutrino excess and predictions for JUNO
Alessandro Granelli, Silvia Pascoli, Salvador Rosauro-Alcaraz
Super-Kamiokande has reported a small excess of electron antineutrino events in the 20 MeV energy range, in the search for the diffuse supernova neutrino background. We interpret this signal as a possible indication of dark matter that annihilates dominantly into neutrinos, pointing to a thermal dark matter candidate with
