# Spectator Higgs field, large-scale gauge fields, and the nonminimal coupling to gravity

@article{Giovannini2017SpectatorHF, title={Spectator Higgs field, large-scale gauge fields, and the nonminimal coupling to gravity}, author={Massimo Giovannini}, journal={Physical Review D}, year={2017}, volume={95}, pages={083501} }

Even if the Higgs field does not affect the evolution of the background geometry, its massive inhomogeneities induce large-scale gauge fields whose energy density depends on the slow-roll parameters, on the effective scalar mass and, last but not least, on the dimensionless coupling to the space-time curvature. Since the non-Abelian gauge modes are screened, the non-minimal coupling to gravity predominantly affects the evolution of the hypercharge and electromagnetic fields. While in the case…
