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…

Triplet Higgs assisted leptogenesis from axion oscillation after inflation
Sasmita Mishra
Leptogenesis via axion oscillation after inflation is an alternate mechanism of thermal leptogenesis. In this mechanism, the requirement of the existence of a lepton number () v…

Triplet scalar flavored leptogenesis with spontaneous CP violation
Sreerupa Chongdar, Sasmita Mishra
The inclusion of two triplet scalars in the Standard Model (SM) enables to accommodate neutrino mass generation as well as baryogenesis through leptogenesis. One of the essential i…
