Massive Gravity and Lorentz Symmetry

Abstract

We consider Lorentz-symmetry properties of the ghost-free massive gravity theory proposed by de Rham, Gabadadze, and Tolley. In particular, we present potentially observable effects in gravitational-wave propagation and in Newton's law, including Lorentz-violating signals.
