Description

Neutrino self-interactions can play an essential role in the origin of dark matter. The existence of these new neutrino interactions may manifest itself in next-generation experiments, including DUNE. I will present an anatomy of production mechanisms for sterile neutrino dark matter in the presence of secret interactions among active neutrinos. I will also present the effects of a scalar-mediated neutrino self-interaction on the supernova cooling luminosity, which allows to constrain the self-interaction parameter space in a complementary way to terrestrial experiments or cosmological probes.
