COSMOLOGICAL AND PARTICLE PHYSICS IMPLICATIONS OF A NON-MINIMAL RADIATIVE HIGGS INFLATION

Abstract

In this work, we explore aspects of a Non-Minimal Higgs Inflation model, where radiative corrections are included in the Coleman-Weinberg approximation. By means of a MCMC analysis, we constrain the parameter that quantifies the quantum corrections to the potential with cosmological data for a range of the inflationary e-fold number. Also, we perform a general analysis of the reheating stage, in order to estimate an upper limit to the inflationary expansion. In the interest of better understanding the effects of the proposed scenario at low energies, we relate our constraints in the radiative parameter with particle physics measurements at the electroweak scale, via the Renormalization Group Equations, which allows us to estimate a limit to the top quark mass. Finally, we investigate the breaking of the correlation between the Hubble constant and the clustering parameter, rendering the model interesting in light of the cosmological tensions discussed in the last decade.
