Abstract

The search for Lorentz Invariance Violation (LIV) is strictly connected with the high-energy structure of space-time. In the model we developed, LIV is introduced from modified dispersion relations (MDR) and a metric structure is preserved in Finsler geometry. The MDR corrections are represented by homogenous functions, introducing LIV sources of kinematical origin, without any new interaction. The Standard Model symmetries and the space isotropy are preserved. Every particle experiences its own limit velocity, as a function of its momentum, and the modifications of the neutrino propagation equations induce additional corrections to the standard flavor oscillation pattern. Their impact on the oscillation probabilities is analyzed for many cases of phenomenological relevance.
