Low scale leptogenesis and dark matter in the presence of primordial black holes
Suruj Jyoti Das, Devabrat Mahanta, Debasish Borah
We study the possibility of low scale leptogenesis along with dark matter (DM) in the presence of primordial black holes (PBH). For a common setup to study both leptogenesis and DM…

Gravitational origin of dark matter and Majorana neutrino mass with non-minimal quartic inflation
Debasish Borah, Suruj Jyoti Das, Abhijit Kumar Saha
We propose a minimal framework to address successful quartic inflation, dark matter (DM) production in the early universe and non-vanishing tiny Majorana neutrino mass from a commo…

Cosmic Inflation in Minimal Model: Implications for (Non) Thermal Dark Matter and Leptogenesis
Debasish Borah, Suruj Jyoti Das, Abhijit Kumar Saha
We study the possibility of realising cosmic inflation, dark matter (DM), baryon asymmetry of the universe (BAU) and light neutrino masses in non-supersymmetric minimal gauged $B-L…
