Effects of discontinuities of the derivatives of the inflaton potential

ABSTRACT: We study the effects of a class of features of the inflaton potential, corresponding to discontinuities in its derivatives. We perform fully numerical calculations and derive analytical approximations for the curvature perturbations spectrum and the bispectrum which are in good agreement w...
