Chaotic inflation with four-form couplings
We consider chaotic inflation models with a pseudoscalar field containing the general couplings to the four-form flux. The four-form mixing with the pseudoscalar field induces a quadratic potential for inflaton while the coexisting four-form mixing with graviton generates a nonminimal gravity coupli...
