A note on particle kinematics in Horava-Lifshitz scenarios

arXiv:0910.1329

Abstract

In this short note we clarify a link between anisotropic-scaling scenarios and Finsler spacetimes. Generalizing earlier analysis it is shown that the kinematics of propagating particles (in the sense of geometrical optics) can be described in terms of (pseudo-)Finsler structures.
