Description

We will discuss the various possibilities of beyond Standard Model
scenarios involving Type-I seesaw and Inverse seesaw mechanism. The B-L
gauge extension with a scalar dark matter scenario can have displaced decay
signature while the dark matter freeze-out is via right-handed neutrino pair. The
Type-X 2HDM is motivated to explain the muon (g-2) excess, if associated with the
right-handed neutrinos, can lead to a new decay mode of charged Higgs decaying
to charged lepton and the right-handed neutrino. A Type-I seesaw extension with
one more Majorana fermion and singlet scalar can lead to loop induced dark
matter-Higgs coupling and also gives rise to interesting phenomenology for the
freeze-out and freeze-in scenarios.
