Testing MeV dark matter with neutrino detectors

Understand

MeV particles have been advocated as Dark Matter (DM) candidates in different contexts.

• This hypothesis can be tested indirectly by searching for the Standard Model (SM) products of DM self-annihilations.
• As the signal from DM self-annihilations depends on the square of the DM density, we might expect a sizable flux of annihilation products from our galaxy.
• Neutrinos are the least detectable particles in the SM and a null signal in this channel would allow to set the most conservative bound on the total annihilation cross section.
