Anatomy of singlet-doublet dark matter relic: annihilation, co-annihilation, co-scattering, and freeze-in
Partha Kumar Paul, Sujit Kumar Sahoo, Narendra Sahu
The singlet-doublet vector-like fermion dark matter model has been extensively studied in the literature over the past decade. An important parameter in this model is the singlet-d…
Thermal leptogenesis, dark matter, and gravitational waves from an extended canonical seesaw scenario
Partha Kumar Paul, Narendra Sahu, Prashant Shukla
In a canonical type-I seesaw scenario, the Standard Model is extended with three singlet right-handed neutrinos (RHNs) with masses to simultaneously e…
New realisation of light thermal dark matter with enhanced detection prospects
Amit Adhikary, Debasish Borah, Satyabrata Mahapatra +3
Light dark matter (DM) with mass around the GeV scale faces weaker bounds from direct detection experiments. If DM couples strongly to a light mediator, it is possible to have obse…
Asymmetric self-interacting dark matter with a canonical seesaw model
Debasish Borah, Satyabrata Mahapatra, Partha Kumar Paul +2
We study the possibility of generating dark matter (DM) and baryon asymmetry of the Universe (BAU) simultaneously in an asymmetric DM framework, which also alleviates the small-sca…
Light thermal dark matter via type-I seesaw portal
Debasish Borah, Pritam Das, Satyabrata Mahapatra +1
We propose a minimal scenario for light thermal dark matter (DM) in sub-GeV to GeV range by incorporating a scalar singlet DM in a type-I seesaw scenario extended by an additional…
