Scalaron–Higgs inflation reloaded: Higgs-dependent scalaron mass and primordial black hole dark matter

Abstract We propose an extension of the scalaron-Higgs model by a non-minimal coupling of the Standard Model Higgs boson to the quadratic Ricci scalar resulting in a Higgs-dependent scalaron mass. The model predicts a successful stage of effective single-field Starobinsky inflation. It features a mu...
