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…
Singlet-Doublet Majorana Dark Matter and Neutrino Mass in a minimal Type-I Seesaw Scenario
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
In a bid to simultaneous explanation of dark matter (DM) and tiny but non-zero masses of left-handed neutrinos, we propose a minimal extension of the Standard Model (SM) by a vecto…
Flavoured gauge extension of singlet-doublet fermionic dark matter: neutrino mass, high scale validity and collider signatures
Basabendu Barman, Debasish Borah, Purusottam Ghosh +1
We propose an Abelian gauged version of the singlet-doublet fermionic dark matter (DM) model where DM, combination of a vector like fermion doublet and a fermion singlet, is natura…
Two component dark matter with inert Higgs doublet: neutrino mass, high scale validity and collider searches
Subhaditya Bhattacharya, Purusottam Ghosh, Abhijit Kumar Saha +1
The idea of this work is to investigate the constraints on the dark matter (DM) allowed parameter space from high scale validity (absolute stability of Higgs vacuum and perturbativ…
SIMPler realisation of Scalar Dark Matter
Subhaditya Bhattacharya, Purusottam Ghosh, Shivam Verma
With growing agony of not finding a dark matter (DM) particle in direct search experiments so far (for example in XENON1T), frameworks where the freeze-out of DM is driven by numbe…
