Leptogenesis from spontaneous symmetry breaking during inflation

Leptogenesis from spontaneous symmetry breaking during inflation

Abstract Symmetry breaking in the Higgs field via a non-minimal coupling to gravity or higher-dimensional interactions with the inflaton can lead to condensation at a large vacuum expectation value (VEV) during inflation. After inflation is over, the Higgs field must relax to the minimum of its effe...
