Will MINOS see new physics?

TL;DR

This paper investigates how non-standard neutrino interactions could enhance flavor transition probabilities, potentially allowing MINOS to detect signals beyond standard predictions and significantly affecting future neutrino experiments.

Contribution

It provides a model-independent analysis showing that non-standard interactions can greatly increase neutrino flavor transition probabilities, impacting experimental observations.

Findings

MINOS may observe an enhanced $ u_ o u_e$ signal due to non-standard interactions.

The $ u_e o u_ au$ channel at a neutrino factory could be significantly amplified.

Non-standard interactions can produce observable effects beyond standard model expectations.

Abstract

The effect of non-standard neutrino interactions with matter at long baseline neutrino experiments is examined in a model independent way, taking into account the constraints from all the experiments. It is found that such a non-standard interaction can enhance the flavor transition probability so significantly that the ongoing experiment MINOS may see the signal of $\nu_\mu\to\nu_e$ which is much more than the prediction by the standard scenario. It is also found that the silver channel $\nu_e\to\nu_\tau$ at a neutrino factory could have a huge enhancement.
