Spacetime curvature and the Higgs stability during and after inflation: Gravity to the rescue?

Abstract

We investigate the stability of the electroweak vacuum during and after inflation by taking into account the effects of classical gravity in the quantum dynamics. In particular we show that the possible instability may be avoided without any beyond the Standard Model physics. Talk presented at the 27th Rencontres de Blois on Particle Physics and Cosmology.
