Near-inflection point inflation and production of dark matter during reheating
Anish Ghoshal, Gaetano Lambiase, Supratik Pal +2
We study slow roll single field inflationary scenario and the production of non-thermal fermionic dark matter, together with standard model Higgs, during reheating. For the inflati…
Signatures of Non-thermal Dark Matter with Kination and Early Matter Domination: Gravitational Waves versus Laboratory Searches
Anish Ghoshal, Lucien Heurtier, Arnab Paul
The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in l…
Constraints on Dark Matter-Neutrino Interaction from 21-cm Cosmology and Forecasts on SKA1-Low
Antara Dey, Arnab Paul, Supratik Pal
In this article, we have done a thorough investigation of the possible effects of interaction between dark matter (DM) and neutrinos on reionization history. We have constrained th…
Inflection-point Inflation and Dark Matter Redux
Anish Ghoshal, Gaetano Lambiase, Supratik Pal +2
We investigate for viable models of inflation that can successfully produce dark matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic Microwave Backg…
eV Hubble Scale Inflation with Radiative Plateau: Very light Inflaton, Reheating & Dark Matter in B-L Extensions
Anish Ghoshal, Nobuchika Okada, Arnab Paul
We study radiative plateau-like inflation \& Z-portal freeze-in fermionic dark matter (DM) in a minimal B-L extended model. The U(1) Higgs, responsible for heavy neu…
Radiative Plateau Inflation with Conformal Invariance: Dynamical Generation of Electroweak and Seesaw Scales
Anish Ghoshal, Nobuchika Okada, Arnab Paul
We investigate a scale-invariant scenario where the Standard Model (SM) is supplemented with a dark scalar which has gauge \& Yukawa interactions, with the couplings $g_{…
