Implications of lepton flavor violation on long baseline neutrino oscillation experiments

Abstract

Nonstandard neutrino interactions (NSIs), the subleading effects in the flavor transitions of neutrinos, play a crucial role in the determination of the various unknowns in neutrino oscillations, such as neutrino mass hierarchy, the Dirac CP violating phase, and the octant of the atmospheric mixing angle. In this work, we focus on the possible implications of lepton flavor violating (LFV) NSIs, which generally affect the neutrino propagation, on the determination of these unknown oscillation parameters. We study the effect of these NSIs on the physics potential of the currently running and upcoming long-baseline experiments, i.e., T2K, NOνA, and DUNE. We also check the allowed oscillation parameter space in the presence of LFV NSIs.
