Probing Non Standard Neutrino Physics at T2KK and Neutrino Factory

TL;DR

This paper explores how future long baseline neutrino experiments like T2KK and neutrino factories can detect or constrain non-standard neutrino interactions, especially addressing the $ heta_{13}$-NSI confusion problem.

Contribution

It proposes specific experimental setups with dual detectors at different baselines to enhance sensitivity to non-standard neutrino interactions and resolve parameter degeneracies.

Findings

Neutrino factory with 3000 km and 7000 km detectors improves NSI sensitivity.

Dual-detector setup helps distinguish between standard and non-standard interactions.

The proposed configurations can potentially resolve the $ heta_{13}$-NSI confusion.

Abstract

We discuss the possibility of constraining or discovering the non-standard neutrino physics beyond the standard model with future long baseline neutrino oscillation experiments. Among very many possible experimental set up we discuss neutrino factory and T2KK, in which two detector setting may be useful to achieve the goal. In particular, neutrino factory with two detectors at baselines of 3000 km and 7000 km have a great sensitivity to non-standard interaction (NSI) and solve the $\theta_{13}$-NSI confusion problem.
