In theories with extra dimensions it is well known that the Lorentz invariance of the D = 4+n-dimensional spacetime is lost due to the compactified nature of the n dimensions leaving invariance only in 4d. In such theories other sources of Lorentz violation may exist associated with the physics that initiated the compactification process at high scales. Here we consider the possibility of capturing some of this physics by analyzing the higher dimensional analog of the model of Colladay and…
