On the primordial black hole mass function for broad spectra
Valerio De Luca, Gabriele Franciolini, Antonio Riotto
Abstract
We elaborate on the mass function of primordial black holes in the case in which the power spectrum of the curvature perturbation is broad. For the case of a broad and flat spectrum, we argue that such a mass function is peaked at the smallest primordial black mass which can be formed and possesses a tail decaying like M−3/2, where M is the mass of the primordial black hole.
