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 1014gMPBH1038g10^{14}\mathrm{g}\le M_\mathrm{PBH}\le 10^{38}\mathrm{g} when curvaton inflation gives the number of e-foldings 5N2385\leq N_2\leq 38. The non-Gaussianity of the inflating curvaton does not prevent the PBH formation.
