Will atmospheric neutrino experiment at Hyper-Kamiokande see non-standard interaction effects?

TL;DR

This paper explores whether the Hyper-Kamiokande atmospheric neutrino experiment can detect non-standard flavor-dependent interactions that might resolve existing discrepancies in neutrino mass-squared difference measurements.

Contribution

It assesses the potential of Hyper-Kamiokande to observe non-standard neutrino interactions proposed to explain experimental tensions.

Findings

Hyper-Kamiokande could detect non-standard interactions if they exist.

The experiment can test flavor-dependent interaction hypotheses.

Potential to resolve neutrino oscillation measurement discrepancies.

Abstract

In this talk we discuss the possibility to test the hypothesis, which has been proposed to explain the tension between the mass-squared differences of the solar neutrino and KamLAND experiments by the non-standard flavor-dependent interaction in neutrino propagation, with the atmospheric neutrino observations at the future Hyper-Kamiokande experiment.
