Dynamics of cosmological inflation and predictions for reheating in the light of 2018 PLANCK results

We study the dynamics of two concrete inflationary models, namely spontaneous symmetry breaking inflation and loop inflation. We constrain the parameters for which a viable inflationary Universe emerges using the latest PLANCK results of last year, and we give predictions for the duration of reheating as well as for the reheating temperature after inflation. Our numerical results show that baryogenesis via leptogenesis may be realized within the inflationary models considered in this work.
