Physics & Astronomy Colloquium – Fall 2021 – Arindam Das

Neutrino oscillation and flavor mixings have proved the existence of tiny neutrino mass. It strongly suggests scenarios involving the physics beyond the Standard Model (SM). To explain the origin of the tiny neutrino mass a plethora of models have been proposed. The tree level neutrino mass models are simple extensions of the SM. Apart from explaining the origin of tiny neutrino mass such scenarios can explain a variety of beyond the SM aspects.  In this talk, we will explore parameters of such models which could be probed at energy, intensity and cosmic frontiers in the near future.
