Probing Lorentz Invariance Violation with Neutrino Factories

Abstract

In this article we show the modification in the number of neutrino events ($\hat{I}{½}_{\hat{I}}¼+\bar{\hat{I}}{½}_{\hat{I}}¼$) caused by Lorentz Invariant Violation (LIV), $\ddot{I}ƒ=5\times 10^{-24}$ and $10^{-23}$, in neutrino oscillation for a neutrino factory at a distance of 7500 km. The momentum of the muons can vary from 10-50 GeV and we consider $2\times 10^{20}$ decays per year. The modifications in the number of events caused by this $\ddot{I}ƒ$ LIV parameter could be a strong signal of new physics in a future neutrino factory.
