Massive Gravity and Lorentz Symmetry
arXiv:2301.13180
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.
