Leptogenesis with sub-electroweak-scale reheating temperature
Basabendu Barman, Arindam Basu, Debasish Borah +1
We study the generation of the baryon asymmetry of the Universe via leptogenesis during the post-inflationary reheating epoch, considering reheating temperatures below the temperat…
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,…
Cogenesis of visible and dark matter in type-I Dirac seesaw
Debasish Borah, Partha Kumar Paul, Narendra Sahu
We propose a novel cogenesis framework based on the type-I Dirac seesaw mechanism. The minimal type-I Dirac seesaw with three heavy vector-like fermions , one singlet scalar $…
Multi-peaked high-frequency gravitational waves from PBH-assisted leptogenesis
Debasish Borah, Nayan Das
We study the possibility of probing non-thermal leptogenesis with multi-peaked high-frequency gravitational waves (GW) by considering heavy right-handed neutrino (RHN) produced fro…
Gravitational waves from seesaw assisted collapsing domain walls
Debasish Borah, Indrajit Saha
Spontaneous breaking of discrete symmetries like leads to the formation of stable topological defects such as domain walls which, if allowed to dominate, can potentially be i…
Probing Dynamical Inverse Seesaw 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…
