Description
We present a renormalizable framework to embed inflation and dark matter (DM) by extending the standard model (SM) with one gauge singlet real scalar field $\phi$ and one gauge singlet fermonic field $\chi$. In our setup, the real scalar field acts as inflaton, and its potential is the most general renormalizable polynomial up to quartic term, which becomes flat due to the existence of a (near) inflection-point. The inflationary predictions agree with the latest CMB experiments very well. We also analyze reheating by considering the Higgs production via inflaton decay. In our scenario DM $\chi$ particles can be produced via decay of inflaton, freeze-in mechanism or gravitational scattering of inflaton/SM plasma depending on the model parameter considered.
