Gravitational corrections to Higgs potentials
arXiv:1710.02987 · doi:10.1007/JHEP04(2018)071
Abstract
Understanding the Higgs potential at large field values corresponding to scales in the range above is important for questions of vacuum stability, particularly in the early universe where survival of the Higgs vacuum can be an issue. In this paper we show that the Higgs potential can be derived in away which is independent of the choice of conformal frame for the spacetime metric. Questions about vacuum stability can therefore be answered unambiguously. We show that frame independence leads to new relations between the beta functions of the theory and we give improved limits on the allowed values of the Higgs curvature coupling for stability.
