Dark matter motivated sterile neutrino contribution to neutrinoless double beta decay
Debashree Priyadarsini Das, Sasmita Mishra
The exact seesaw relation in a type-I seesaw framework puts constraints on the relations between active and sterile neutrino sectors in terms of their masses and mixing angles. In…

Two-sector leptogenesis in a two-Higgs-doublet model with spontaneous CP violation
Debashree Priyadarsini Das, Joy Ganguly, Sasmita Mishra
The extension of the Standard Model (SM) field content with one inert Higgs doublet (IHD) and three right-handed neutrinos (RHNs) is a well-motivated approach. The key advantages o…

Study of neutrinoless double beta decay in the Standard Model extended with sterile neutrinos
Debashree Priyadarsini Das, Sasmita Mishra
We study a model where the Standard Model is augmented with three sterile neutrinos. By adopting a particular parameterization of a unitary matrix - in this context, l…
