Description

Current measurements of the Higgs boson and top quark mass favor metastability of the electroweak vacuum in the Standard Model. This raises some questions when we consider the evolution of our universe: how did it end up in such an energetically disfavored state? Why it remained there during inflation? These problems can be addressed by assuming for the Higgs a direct coupling with the inflaton and/or a non-minimal coupling to gravity. In this talk I will review the effects of these interactions on the Higgs dynamics during the inflationary period and the subsequent period of particle production, namely reheating.
