Lorentz violation and the speed of gravitational waves in brane-worlds
arXiv:gr-qc/0702103 · doi:10.1016/j.physletb.2007.02.032
Abstract
Lorentz violation in a brane-world scenario is presented and used to obtain a relationship between the speed of gravitational waves in the bulk and that on the brane. Lorentz violating effects would manifest themselves in gravitational waves travelling with a greater speed in the bulk than on the brane and this effect is independent of the signature of the extra dimension.
