Abstract
We study models with several scalar doublets where the inert doublets have a nonminimal coupling to gravity and play the role of the inflaton. We allow for this coupling to be complex, thereby introducing violation—a necessary source of the baryon asymmetry—in the Higgs-inflaton couplings. We investigate the inflationary dynamics of the model and discuss how the violation of the model is imprinted on the particle asymmetries after inflation in the hot big bang universe.
