Description
Primordial black holes (PBHs), produced in the early universe, can be responsible for many phenomena, ranging from dark matter to gravitational waves. In this work, we introduce a scenario where the Standard Model Higgs running induces features in the inflationary potential motivated by Higgs inflation. We identify that a near-inflection point or a tachyonic instability can develop in the potential, depending on the specific parameter ranges. We demonstrate how enhanced curvature perturbations can be produced in both scenarios and provide specific mass ranges for the produced PBHs and the corresponding second-order gravitational wave spectra. We show that each scenario can be distinguished with the gravitational wave spectrum and highlight its implication with current and future gravitational wave observatories.
