Finite Temperature NLO Corrections in Relativistic Scatterings: Implications for Dark Matter Freeze-In
Sampriti Roy, Pritam Sen, Satyanarayan Mukhopadhyay
We study the next-to-leading order (NLO) virtual and thermal corrections to relativistic scattering processes involving scalar particles in the early Universe the…
Prospects of measuring the atmospheric muon neutrino and anti-neutrino flux ratio with the ATLAS detector
Deep Ghosh, Satyanarayan Mukhopadhyay, Biswarup Mukhopadhyaya
There is a significant uncertainty in the prediction of atmospheric muon neutrino and anti-neutrino flux ratio using different flux models, especially at higher energies. We study…
Cosmological implications of inflaton-mediated dark and visible matter scatterings after reheating
Deep Ghosh, Sourav Gope, Satyanarayan Mukhopadhyay
The initial density of dark matter (DM) particles, otherwise secluded from the standard model (SM), may be generated at reheating, with an initial temperature ratio for internal th…
Cannibal dark matter decoupled from standard model: cosmological constraints
Avirup Ghosh, Sourav Gope, Satyanarayan Mukhopadhyay
An internally thermalized dark matter (DM) with only gravitational interaction with the standard model (SM) particles at low temperatures, may undergo number-changing self-scatteri…
Momentum distribution of dark matter produced in inflaton decay: effect of inflaton mediated scatterings
Avirup Ghosh, Satyanarayan Mukhopadhyay
Post-inflationary reheating is a widely discussed mechanism for non-thermal production of dark matter (DM). In this scenario the momentum distribution of the produced DM particles…
Cosmology of complex scalar dark matter: interplay of self-scattering and annihilation
Avirup Ghosh, Deep Ghosh, Satyanarayan Mukhopadhyay
The cosmology of a standard model (SM) gauge singlet complex scalar dark matter (DM), stabilized by a reflection symmetry, is studied including all renormalizable interactions that…
