Near-inflection point inflation and production of dark matter during reheating

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 inflationary scenario, we have considered two models of polynomial potential - one is symmetric about the origin and another one is not. We fix the coefficients of the potential from the current Cosmic Microwave Background (CMB) data from Planck/Bicep. Next, we explore the allowed parameter space on the coupling $(y_\chi)$ with inflaton and mass $(m_\chi)$ of dark matter (DM) particles $(\chi)$ produced during reheating and satisfying CMB and several other cosmological constraints.Comment: Prepared for Proceedings of XXV Bled Workshop "What comes beyond the Standard models?
