Towards Testable Type-III Leptogenesis in Non-Standard Early Universe Scenarios
Simran Arora, Devabrat Mahanta
Leptogenesis is an elegant way to explain the baryon asymmetry of the Universe in connection to the neutrino mass and mixing. Although leptogenesis from the decay of a heavy Majora…
Leptogenesis from Dark Matter Coannihilation
Simran Arora, Debasish Borah, Arnab Dasgupta +2
We propose a minimal extension of the type-I seesaw model to realise leptogenesis from the co-annihilation of dark sector particles. The type-I seesaw model is extended with a sing…
Gravitational wave signatures of dark sector portal leptogenesis
Debasish Borah, Devabrat Mahanta, Indrajit Saha
We study the possibility of probing leptogenesis via stochastic gravitational waves (GW) arising from a dark sector assisted first-order electroweak phase transition. The same dark…
Two-component Dark Matter and low scale Thermal Leptogenesis
Subhaditya Bhattacharya, Devabrat Mahanta, Niloy Mondal +1
The observable cosmos exhibits sizable baryon asymmetry, small active neutrino masses, and the presence of dark matter (DM). To address these phenomena together, we propose a two c…
TeV Scale Resonant Leptogenesis with triplet Fermion in Connection to Muon
Simran Arora, Devabrat Mahanta, B. C. Chauhan
We propose an extension of the minimal scotogenic model with a triplet fermion and a singlet scalar. An imposed symmetry allows only diagonal Yukawa couplings a…
Low Scale Leptogenesis in Singlet-Triplet Scotogenic Model
Labh Singh, Devabrat Mahanta, Surender Verma
The scotogenic model presents an elegant and succinct framework for elucidating the origin of tiny neutrino masses within the framework of the Standard Model, employing radiative c…
