[1106.0328] R^n gravity and the chameleon

Authors: Valerio Faraoni (Bishop's University)

Date: 1 Jun 2011

Abstract: The Solar System bounds on Rˆn gravity are often ignored in the literature by invoking the chameleon mechanism. We show that in order for the latter to work, the exponent n must be ridicolously close to unity and, therefore, these theories are severely constrained.
