More on Non-standard Interaction at MINOS

TL;DR

This paper investigates how non-standard neutrino interactions could significantly affect the nu_e appearance results in the MINOS experiment, highlighting potential deviations from standard oscillation predictions and implications for future constraints.

Contribution

It analyzes the impact of complex phases and uncertainties in mixing angles on non-standard neutrino interactions in MINOS, providing new insights into their effects on oscillation probabilities.

Findings

Non-standard interactions can cause large oscillation probabilities beyond standard expectations.

Constraints on non-standard effects can be improved if nu_e appearance is not observed.

Complex phases significantly influence the oscillation outcomes.

Abstract

We discuss about effects of the non-standard interaction of neutrinos with matter on the nu_e appearance search in the MINOS experiment. We consider the effects of the complex phase of the interaction and of the uncertainty on theta_23 also. We show that the oscillation probability can be so large that can not be explained by the ordinary oscillation. We show also how much constraints on the non-standard effects can be improved if the experiment does not observe nu_e appearance signal.
