Reheating predictions in non-minimally coupled inflationary models with radiative corrections

We study the reheating predictions in the non-minimally coupled inflationary model of the quartic inflationary potential, both without and with the self-induced radiative corrections of the inflaton taken into account. We compare these predictions between two different formalisms of gravity: metric and Palatini, and between two different prescriptions of the radiative corrections. We find that the radiative corrections have a non-negligible influence on reheating predictions although two different prescriptions almost give the same results. Different formalisms of gravity lead to different reheating predictions, and the difference becomes more apparent when the radiative corrections are considered.(c) 2023 Elsevier B.V.
