Leptogenesis and Planck-scale black hole remnants in a Pati-Salam cosmology
Arnab Chaudhuri, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
We study leptogenesis and Planck-scale remnant dark matter from primordial black hole (PBH) evaporation in a minimal Pati-Salam cosmology, with the gauge symmetry broken before inf…
Non-Markovian Electroweak Baryogenesis: Memory Effects on CP-Violating Transport and Gravitational Waves
Arnab Chaudhuri
We develop a non-Markovian extension of electroweak baryogenesis within the Schwinger--Keldysh real-time effective field theory framework and the Kadanoff--Baym hierarchy. When the…
Memory-Burden Suppression of Hawking Radiation and Neutrino Constraints on Primordial Black Holes
Arnab Chaudhuri
We investigate the impact of quantum gravitational memory-burden effects on high-energy neutrino signals from evaporating primordial black holes and the resulting constraints from…
Dark Temperature Hierarchies and Gravitational Waves from the Electroweak Phase Transition
Arnab Chaudhuri
We investigate the impact of a semi-decoupled dark sector with a temperature hierarchy relative to the Standard Model plasma on the electroweak phase transition and its associated…
Primordial black hole evaporation in a thermal bath and gravitational waves
Arnab Chaudhuri, Kousik Loho
Primordial black holes (PBHs) formed in the early Universe evaporate via Hawking radiation and constitute a generic source of stochastic gravitational waves. Existing studies of gr…
