Singlet-doublet dark matter induced radiative neutrino mass and TeV scale leptogenesis
The research explores how Singlet-Doublet Dark Matter models can simultaneously explain tiny neutrino masses, dark matter relic density, and the observed baryon asymmetry through TeV-scale leptogenesis. It investigates two setups: Majorana and Dirac scenarios, showing that light neutrino masses arise at one loop level due to the same particles responsible for dark matter and leptogenesis.
