Probing the violation of equivalence principle at a muon storage ring via neutrino oscillation

Abstract

We examine the possible tests of violation of the gravitational equivalence principle (VEP) at a muon storage ring via neutrino oscillation experiments. If the gravitational interactions of the neutrinos are not diagonal in the flavour basis and the gravitational interaction eigenstates have different couplings to the gravitational field, this leads to the neutrino oscillation. If one starts with ${\mu }^{+}$ beam then appearance of ${\tau }^{\pm }$, $e^{+}$ and ${\mu }^{-}$ in the final state are the signals for neutrino oscillation. We have estimated the number of ${\mu }^{-}$ events in this scenario in ${\nu }_{\mu }-N$ deep inelastic scattering. Final state lepton energy distribution can be used to distinguish the VEP scenario from the others. A large area of VEP parameter space can be explored at a future muon storage ring facility with moderate beam energy.
