Abstract

We discuss here possible tests for Palatini f(R)-theories together with their  implications for different formulations of the Equivalence Principle. We shall show that Palatini f(R)-theories  obey the Weak Equivalence Principle and violate the Strong Equivalence Principle. The violations of the Strong Equivalence Principle vanish in vacuum (and purely electromagnetic) solutions as well as on short time scales  with respect to the age of the universe. However, we suggest that a framework based on Palatini f(R)-theories  is more general than standard General Relativity (GR) and it sheds light on the interpretation of data and results in a way which is more model independent than standard GR itself.
