The authors' main claim In particular, consideration of the gravi-Cerenkov radiation of Kaluza-Klein gravitons by ultra-high energy cosmic rays leads to a stringent limit on the fractional difference between the graviton and photon speeds in RS-like models: it must be less than a part in 10^{23}.

In a variant of the Randall-Sundrum braneworld model which has a charged black hole in an anti-de Sitter bulk, the 4D speed of gravity depends upon one's location in the bulk, and in general differs from the speed of light on a given 3-brane. We apply phenomenological constraints on the difference in the speeds of light and gravity to models which use the warping to solve the hierarchy problem. In particular, consideration of the gravi-Cerenkov radiation of Kaluza-Klein gravitons by ultra-high energy cosmic rays leads to a stringent limit on the fractional difference between the graviton and photon speeds in RS-like models: it must be less than a part in 10^{23}.

Original abstract
In a variant of the Randall-Sundrum braneworld model which has a charged black hole in an anti-de Sitter bulk, the 4D speed of gravity depends upon one's location in the bulk, and in general differs from the speed of light on a given 3-brane. We apply phenomenological constraints on the difference in the speeds of light and gravity to models which use the warping to solve the hierarchy problem. In particular, consideration of the gravi-Cerenkov radiation of Kaluza-Klein gravitons by ultra-high energy cosmic rays leads to a stringent limit on the fractional difference between the graviton and photon speeds in RS-like models: it must be less than a part in 10^{23}.

In Refs. [ref] the following relation is found: [equation] where we have adopted the position of Ref. [ref] , in the case where the null energy condition on the brane is not violated, for $w=-1$: [equation] On the other hand, as discussed here, bulk photons propagate with a velocity given by Eq. ([ref]), or equivalently: [equation] where [equation] Taking into account Eq. ([ref]) we find [equation] Then, the difference reads: [equation] We observe that if photons propagate in the bulk then gravitons are not superluminous.

Gravity effects which could reveal 4D Lorentz violation are described in Ref. [ref] (see also Refs. [ref] ) where superluminous propagation of gravitons is possible for specific models with asymmetric solutions.

As a special family of modified gravitational theories, the Lorentz-violating (LV) theories of gravity [ref] , including Hořava-Lifshitz theory [ref] , ghost condensation [ref] , warped brane world [ref] , Einstein-aether theory [ref] and Einstein bumblebee gravity [ref] , have attracted increasing interests.
