Primordial Black Holes from the inflating curvaton
Abstract
The primordial black hole (PBH) formation is studied in light of the inflating curvaton. The typical scale of the PBH formation is determined by curvaton inflation, which may generate PBH with 1014g MPBH 1038g when curvaton inflation gives the number of e-foldings 5≤ N2≤ 38. The non-Gaussianity of the inflating curvaton does not prevent the PBH formation.
