Energy-dependent Boosted Dark Matter from Diffuse Supernova Neutrino Background
Anirban Das, Tim Herbermann, Manibrata Sen +1
Diffuse neutrinos from past supernovae in the Universe present us with a unique opportunity to test dark matter (DM) interactions. These neutrinos can scatter and boost the DM part…
