DESY 08-033 IZTECH-P-08 / 02 Inflation with Non-Minimal Coupling : Metric vs . Palatini Formulations


We analyze non-minimally coupled scalar field theories in metric (second-order) and Palatini (first-order) formalisms in a comparative fashion. After contrasting them in a general setup, we specialize to inflation and find that the two formalisms differ in their predictions for various cosmological parameters. The main reason is that dependencies on the non… (More)
