Event Details

Current experimental sensitivities allow for neutrino scattering to be probed over a range of energy scales and timescales. At the lowest energies, some of the most sensitive probes come from the “MSW matter effect” which allows for background particles to modify neutrino oscillations. This allows for upcoming neutrino oscillation experiments to serve as sensitive probes of neutrino coupling to ordinary matter as well as Dark Matter (DM). Moving up in energy scale, neutrino scattering can produce new “sterile” neutrinos directly in a detector volume. I’ll describe results using IceCube and DM direct detection experiments that have explored this possibility. Lastly I will discuss new results on a model of sterile neutrino DM which can achieve the observed DM relic abundance via neutrino scattering in the early Universe.
