Renormalization group equations of Higgs-R 2 inflation

Abstract

Abstract We derive one- and two-loop renormalization group equations (RGEs) of Higgs-R 2 inflation. This model has a non-minimal coupling between the Higgs and the Ricci scalar and a Ricci scalar squared term on top of the standard model. The RGEs derived in this paper are valid as long as the energy scale of interest (in the Einstein frame) is below the Planck scale. We also discuss implications to the inflationary predictions and the electroweak vacuum metastability.
