Fitting Power Spectrum of Scalar Perturbations for Primordial Black Hole Production during Inflation
A simple phenomenological fit for the power spectrum of scalar (curvature) perturbations during inflation is proposed to analytically describe slow roll of inflaton and formation of primordial black holes (PBH) in the early universe, in the framework of single-field models. The fit is given by a sum...
