Sensitivity of atmospheric neutrino experiments to neutrino non-standard interactions

Abstract

We study the sensitivity of atmospheric neutrino experiments to the neutrino non-standard interactions (NSI) which is motivated by the tension between the two mass squared differences extracted from the KamLAND and solar neutrino experiments. In this study the sensitivity of the future Hyper-Kamiokande experiments for 4438 days to NSI is shown. Assuming that the mass hierarchy is known, we find that the best-fit value from the solar neutrino and KamLAND data can be tested at more than 8 $\sigma$, while the one from the global analysis can be examined at 5.0 $\sigma$ (1.4 $\sigma$) for the normal (inverted) mass hierarchy.
