- W3098093449 abstract "We calculate the mass distribution of Primordial Black Holes (PBHs) produced during metric preheating. After inflation, the oscillations of the inflaton at the bottom of its potential source a parametric resonant instability for small-scale scalar perturbations, that may collapse into black holes. After reviewing in a pedagogical way different techniques that have been developed in the literature to compute mass distributions of PBHs, we focus on the excursion-set approach. We derive a Volterra integral equation that is free of a singularity sometimes encountered, and apply it to the case of metric preheating. We find that if the energy density at which the instability stops, ρΓ, is sufficiently smaller than the one at which inflation ends, ρend, namely if ρΓ1/4/ρend1/4 < 10−5(ρend1/4/1016GeV)3/2, then PBHs dominate the universe content at the end of the oscillatory phase. This confirms the previous analysis of ref. [1]. By properly accounting for the cloud-in-cloud mechanism, we find that the mass distribution is more suppressed at low masses than previously thought, and peaks several orders of magnitude above the Hubble mass at the end of inflation. The peak mass ranges from 10 g to stellar masses, giving rise to different possible cosmological effects that we discuss." @default.
