Viability of Boosted Light Dark Matter in a Two-Component Scenario
Arindam Basu, Amit Chakraborty, Nilanjana Kumar +1
We study the boosted dark matter (BDM) scenario in a two-component model. We consider a neutrinophilic two-Higgs doublet model (2HDM), which consists of one extra Higgs doublet…

Testing leptogenesis and dark matter production during reheating with primordial gravitational waves
Basabendu Barman, Arindam Basu, Debasish Borah +2
We study the generation of baryon asymmetry as well as dark matter (DM) in an extended reheating period after the end of slow-roll inflation. Within the regime of perturbative rehe…

Leptonic CP-violation in the sneutrino sector of the BLSSM with Inverse Seesaw
Arindam Basu, Amit Chakraborty, Yi Liu +2
We study CP violation (CPV) in the sneutrino sector within the B-L extension of the Minimal Supersymmetric Standard Model (BLSSM), wherein an inverse seesaw mechanism has been impl…
