Abstract

Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included R2 term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to MPBH ∈ (1016, 1015)M☉ primordial black holes with significant abundance, which may consist the majority of dark matter.
