Equivalence principle in scalar-tensor gravity (1505.01285v2)
Published 6 May 2015 in gr-qc, astro-ph.CO, and hep-th
Abstract: We present a direct confirmation of the validity of the equivalence principle for unstructured test bodies in scalar tensor gravity. Our analysis is complementary to previous approaches and valid for a large class of scalar-tensor theories of gravitation. A covariant approach is used to derive the equations of motion in a systematic way and allows for the experimental test of scalar-tensor theories by means of extended test bodies.
