Description

We consider the inflation model with non-minimal couplings where a singlet inflaton mixes with the Standard Model Higgs boson. The conditions required for the mixed inflation to happen constrain the Higgs and singlet couplings at unitarity scale, giving rise to additional constraints on the parameter space at low energy. We consider the LEP and electroweak precision data constraints on the singlet-mixed Higgs sector and discuss the implications of our analysis on the discovery potential of the Higgs bosons at colliders. We comment on the unitarity problems in our model.
