Search for Non-Standard Interactions by atmospheric neutrino

TL;DR

This paper explores how atmospheric neutrino experiments can constrain non-standard interactions affecting neutrino propagation, focusing on parameters less constrained by other experiments.

Contribution

It demonstrates the potential of Super-Kamiokande and Hyper-Kamiokande to limit non-standard interaction parameters in neutrino physics.

Findings

Constraints on non-standard interaction parameters derived from atmospheric neutrino data.

Neglecting strongly constrained parameters highlights the remaining viable non-standard interactions.

Potential for future experiments to further tighten these constraints.

Abstract

We investigate the effects of neutral current Non-Standard Interactions in propagation on atmospheric neutrino experiments such as Super-Kamiokande and Hyper-Kamiokande. With the ansatz where the parameters which have strong constraints from other experiments are neglected, we show how these experiments put constraints on the remaining parameters of the Non-Standard Interactions.
