Description

Explorations of the origin of dark matter lead to rich experimental opportunities to discover the underlying new physics. I will discuss light sterile neutrino dark matter that is produced from the Standard Model plasma in the early universe. Leading production mechanisms include out-of-equilibrium neutrino oscillation supplemented by neutrino self-interactions (freeze in) and relativistic thermal freeze out followed by an entropy injection. I will show how the different histories of universe are encoded in the relic dark matter and impact their subsequent evolutions. I will present existing experimental constraints on these possibilities and highlight the complementary probes and new opportunities at upcoming cosmic and neutrino frontiers.
