A covariant approach to the description of a violation of the Weak Equivalence Principle — •Claus Lämmerzahl1,2, Eva Hackmann1, and Meike List11ZARM, University Bremen, Germany — 2IfP, University Oldenburg, Germany

Violations of the Weak Equivalence Principle (WEP) are usually described within the Newtonian framework where masses of different composition couple differently to the gravitational field. Here we develop a covariant formalism and show that violations of the WEP are then described within a kind of bi-metric theory. We describe the consequences of such an ansatz and possible tests of the WEP. Particular features may appear in the strong gravity regime.
