  • 摘要:In this talk we show how future neutrino detectors could be used to break some of the degeneracies in the dark matter (DM) parameter space and to test some of the DM properties. We consider first the case of annihilations inside the Sun and show how detectors with good neutrino energy resolution could help to discriminate between different annihilation channels (soft or hard) and break their degeneracy with the DM-proton elastic scattering cross section. Then, we consider DM annihilations and decays in the galactic halo. By making use of the fact that neutrinos are the least detectable particles of the StandardModel and assuming DM only annihilates or decays into neutrinos, we show how future neutrino detectors could be great tools to obtain general limits on the total DM annihilation cross section and on the DM lifetime.
