Heavy flavour production in the presence of a weak magnetic field
Sudeep Saha, Sandeep Chatterjee, Ujjal Kumar Dey +1
We calculate analytic expression for the cross section up to order for the production of a heavy quark of mass through the gluon fusion process $g+g\to Q…
Gravitational lensing of neutrinos through the lens of decoherence
Bikash Kumar Acharya, Ujjal Kumar Dey
We propose a new source of neutrino decoherence arising from stochastic gravitational lensing by unresolved mass substructure. Unlike traditional models that treat the lensing pote…
High-redshift supermassive black hole population from core-collapse in self-interacting dark matter halos
Sambo Sarkar, Ujjal Kumar Dey
Self-interactions between dark matter (DM) particles facilitate the inter-particle redistribution of energy within the central region of DM halos. Recent studies of dark matter spi…
Enlightening dark moments of neutrino with superradiance
Indra Kumar Banerjee, Ujjal Kumar Dey, Anna John
Neutrinos can acquire electromagnetic moments either within the Standard Model through higher order radiative corrections or within the domain of new physics. In this study we focu…
Stodolsky effect in the framework of Generalised Neutrino Interactions
Siddhartha Bandyopadhyay, Ujjal Kumar Dey
We study the Stodolsky effect utilizing the most general form of neutrino interactions with electrons below the electroweak scale by considering all possible Lorentz invariant oper…
Mini-review on the production of Primordial Black Holes from First-Order Phase Transitions in the Early Universe
Indra Kumar Banerjee, Ujjal Kumar Dey, Shaaban Khalil
We review the creation mechanism of primordial black holes from first order phase transitions. We discuss various model-dependent and independent mechanisms and relate the properti…
