Neutrinos: The Key to the Dark Sector?

Anirban Das

SNU, South Korea

Neutrinos are elusive and one of the best-kept secrets of our Universe. Other than the mass differences and the mixing angles of the three Standard Model neutrino flavors, we do not know much about them. At a time when we do not have any compelling sign of new physics from the dark sector in any experiments, numerous theoretical models/setups have been proposed where the neutrinos hold the key to the dark sector in the form of self-interaction or interaction with dark matter. Some of the models have even claimed to ease the Hubble Tension. In this talk, I will show how nonstandard physics in the neutrino sector could show up as observable signatures, and what the latest experiments can tell us about them.
