Impact of non-standard neutrino interactions on future oscillation experiments

TL;DR

This paper investigates how non-standard neutrino interactions can affect the results of future reactor and superbeam experiments, potentially causing conflicting or inaccurate measurements of the neutrino mixing angle theta-13.

Contribution

It provides a detailed analysis of the impact of complex phases of NSI parameters and near detector observations on neutrino oscillation experiments.

Findings

Reactor and superbeam experiments may yield conflicting theta-13 results due to NSI.

NSI can cause the measured theta-13 to deviate significantly from the true value.

The complex phases of NSI parameters influence experimental outcomes.

Abstract

We study the performance of reactor and superbeam neutrino experiments in the presence of non-standard interactions (NSI). We find that for some non-standard terms, reactor and superbeam experiments would yield conflicting result in the theta-13 determination, while in other cases, they may agree well with each other, but the resulting value for theta-13 could be far from the true value. Throughout our discussion, we pay special attention to the impact of the complex phases of the NSI parameters and to the observations at the near detector.
