INFLATION WITH HIGH DERIVATIVE COUPLINGS

    https://doi.org/10.1142/S0217732307025212Cited by:9 (Source: Crossref)

    We study a class of generalized inflation models in which the inflaton is coupled to the Ricci scalar by a general f(φ, R) term. The scalar power spectrum, the spectral index, the running of the spectral index, the tensor mode spectrum and a new consistency relation of the model are calculated.
