Post-inflationary production of particle Dark Matter: non-minimal Natural and Coleman--Weinberg inflationary scenarios
Anish Ghoshal, Maxim Yu. Khlopov, Zygmunt Lalak +1
We investigate the production of non-thermal fermionic dark matter particles during the reheating era following slow roll inflation, driven by inflaton non-minimally coupled t…

Post-inflationary Leptogenesis and Dark Matter production: Metric versus Palatini formalism
Anish Ghoshal, Zygmunt Lalak, Supratik Pal +1
We investigate production of non-thermal dark matter particles and heavy sterile neutrinos from inflaton during the reheating era, which is preceded by a slow-roll inflationary epo…

Post-inflationary production of particle Dark Matter: Hilltop and Coleman-Weinberg inflation
Anish Ghoshal, Maxim Yu. Khlopov, Zygmunt Lalak +1
We investigate the production of non-thermal dark matter (DM), , during post-inflationary reheating era. For inflation, we consider two slow roll single field inflationary scen…
