Abstract : A class of inflationary models involving rapid bursts of particle production predicts observational signatures, such as bump-like features in the primordial scalar power spectrum. We study such models by comparing their predictions with the latest CMB data from Planck 2018. We perform Bayesian analysis to constrain the parameters of the inflation model. The results of our analysis will be presented.
