Abstract

We discuss models of inflation where the inflaton is non-minimally coupled to gravity in some general setting, focusing on their predictions on inflationary observables such as the spectral index and tensor-to-scalar ratio. We consider both metric and Palatini formalisms of gravity and argue that how some inflation models can be alleviated by introducing a non-minimal coupling to gravity. The issues of distinguishing variants of such models are also discussed.
