Matter-Antimatter Asymmetry from Dirac-Majorana Flip-Flop
Debasish Borah, Arnab Dasgupta, Debalina Nandy +2
The observed matter-antimatter asymmetry can be generated dynamically via leptogenesis, where a non-zero lepton asymmetry is generated first and then gets converted into baryon asy…
Charged scalar portal dark matter with non-restoration and gravitational waves
Debasish Borah, Dhruv Ringe, Indrajit Saha
We explore the possibility of reviving scalar singlet dark matter (DM) with a minimal extension by a charged singlet scalar which also leads to hypercharge non-restoration in the e…
Singlet-Doublet fermion origin of dark matter, neutrino mass and inverse first-order electroweak phase transition
Debasish Borah, Indrajit Saha, Sujit Kumar Sahoo +2
We study the possibility of an inverse first-order electroweak phase transition (IFOEWPT) and observable gravitational waves (GW) in a radiative neutrino mass model of scotogenic t…
Dark Phoenix: dark matter relic from its own decay
Debasish Borah, Satyabrata Mahapatra, Indrajit Saha +2
We propose a novel mechanism for generating correct relic of dark matter (DM) which otherwise gets thermally overproduced from the conventional freeze-out mechanism. The mechanism,…
Probing the dynamical inverse seesaw mechanism with low-frequency gravitational waves
Debasish Borah, Sounak Dutta, Partha Kumar Paul +2
We study the possibility of probing the dynamical inverse seesaw mechanism for the origin of light neutrino masses via the detection of stochastic gravitational waves (GW) in the l…
Imprint of matter-antimatter asymmetry on collapsing domain walls
Dipendu Bhandari, Debasish Borah, Indrajit Saha
Spontaneous breaking of discrete symmetries play non-trivial role in many well-motivated particle physics models. However, it leads to a network of cosmologically unwanted domain w…
Twin-peaked gravitational wave signals from a phase transition
Rishav Roshan, Indrajit Saha
We compute the gravitational wave spectrum from a phase transition associated with the spontaneous breaking of a symmetry. If the transition is second-orde…
