Abstract

In the typical seesaw models, small neutrino mass and cosmic baryon-antibaryon asymmetry are tightly connected while dark matter remains unrelated. In this project, leptogenesis will be studied in thecontext of inert Higgs doublet model and the mirror world model where the connection with dark matter can be established. In the former scenario, the dark matter is determined from the freezeout mechanism while in the latter case, it is determined by the mirror baryon-antibaryon asymmetry.
