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…
Electroweak phase transition in SMEFT: Gravitational wave and collider complementarity
Sahabub Jahedi, Indrajit Saha, Abhik Sarkar
We study the first-order electroweak phase transition (FO-EWPT) within the Standard Model Effective Field Theory (SMEFT) framework induced by dimension-6 operators. Such phenomena…
Gravitational wave signatures of dark sector portal leptogenesis
Debasish Borah, Devabrat Mahanta, Indrajit Saha
We study the possibility of probing leptogenesis via stochastic gravitational waves (GW) arising from a dark sector assisted first-order electroweak phase transition. The same dark…
Filtered cogenesis of PBH dark matter and baryons
Debasish Borah, Indrajit Saha
We propose a novel cogenesis of baryon and dark matter (DM) in the Universe by utilising a first-order phase transition (FOPT) in the dark sector containing an asymmetric Dirac fer…
