Phys. Rev. D 72, 044022 (2005) [6 pages]Parametrized post-Newtonian limit of fourth order gravity inspired by scalar-tensor gravityReceived 22 July 2005; published 25 August 2005 Based on the dynamical equivalence between higher order gravity and scalar-tensor gravity the parametrized post-Newtonian (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. © 2005 The American Physical Society URL:
