Degeneracy in the spectrum and bispectrum among featured inflaton potentials
ABSTRACT: We study the degeneracy of the primordial spectrum and bispectrum of the curvature perturbation in single field inflationary models with a class of features in the inflaton potential. The feature we consider is a discontinuous change in the shape of the potential and is controlled by a cou...
