PPN-limit of Fourth Order Gravity inspired by Scalar-Tensor Gravity

Astrophysics 2008-11-26 v2

Abstract

Based on the {\it dynamical} equivalence between higher order gravity and scalar-tensor gravity the PPN-limit of fourth order gravity is discussed. We exploit this analogy developing a fourth order gravity version of the Eddington PPN-parameters. As a result, Solar System experiments can be reconciled with higher order gravity, if physical constraints descending from experiments are fulfilled.
