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…
Scalar Portal Verifiable Light Dark Matter and Correlated Gravitational Wave Signatures
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
The lack of signals in direct detection experiments has placed the canonical Weakly Interacting Massive Particle (WIMP) paradigm under severe tension, motivating a shift toward the…
Cosmological Origin of the KM3-230213A event and associated Gravitational Waves
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
We propose a novel cosmological scenario to explain the exceptional KM3-230213A neutrino event reported at an energy scale of ~PeV by the KM3NeT collaboration, al…
Reconciling Cosmological Tensions with Inelastic Dark Matter and Dark Radiation in a Framework
Wonsub Cho, Ki-Young Choi, Satyabrata Mahapatra
We propose a novel and comprehensive particle physics framework that addresses multiple cosmological tensions observed in recent measurements of the Hubble parameter, , and Ly…
Gravitational Wave Sourced by Decay of Massive Particle from Primordial Black Hole evaporation
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
In this article, we investigate the stochastic gravitational waves (GWs) spectrum, resulting from the emission of gravitons through bremsstrahlung, in the decay of particles produc…
