We refine and update the metastability constraint on the standard model (SM) top and Higgs masses by analytically including gravitational corrections to the vacuum decay rate.

Abstract

We refine and update the metastability constraint on the standard model (SM) top and Higgs masses by analytically including gravitational corrections to the vacuum decay rate. Present best-fit ranges of the top and Higgs masses mostly lie in the narrow metastable region. Furthermore, we show that the SM potential can be fine-tuned in order to be made suitable for inflation. However, SM inflation results in a power spectrum of cosmological perturbations not consistent with observations.
