Self-interacting freeze-in dark matter in a singlet doublet scenario
Purusottam Ghosh, Partha Konar, Abhijit Kumar Saha +1
We examine the non-thermal production of dark matter in a scalar extended singlet doublet fermion model where the lightest admixture of the fermions constitutes a suitable dark mat…
Shedding Flavor on Dark via Freeze-in: Gauged Extensions
Basabendu Barman, Purusottam Ghosh, Anish Ghoshal +1
We consider a singlet fermionic dark matter (DM) in a gauged extension of the Standard Model (SM), with , and derive bounds on the allowed param…
TeV Scale Modified Type-II Seesaw and Dark Matter in a Gauged Symmetric Model
Purusottam Ghosh, Satyabrata Mahapatra, Nimmala Narendra +1
In an endeavor to explain the light neutrino masses and dark matter (DM) simultaneously, we study a gauged extension of the standard model (SM). The neutrino masse…
Majorana Dark Matter and Neutrino mass in a singlet-doublet extension of the Standard Model
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
A minimal extension of the Standard Model (SM) by a vector-like fermion doublet and three right handed (RH) singlet neutrinos is proposed in order to explain dark matter and tiny n…
Scalar Multiplet Dark Matter in a Fast Expanding Universe: resurrection of the desert region
Basabendu Barman, Purusottam Ghosh, Farinaldo S. Queiroz +1
We examine the impact of a faster expanding Universe on the phenomenology of scalar dark matter (DM) associated with multiplets. Earlier works with radiation dominated Un…
