# Exploring New Physics from nu_tau events in OPERA

## TL;DR

This paper investigates how tau neutrino events in OPERA can constrain new physics models, including non-standard interactions and sterile neutrinos, by analyzing experimental data.

## Contribution

It provides a detailed analysis of OPERA tau neutrino data to limit non-standard interaction parameters and sterile neutrino models.

## Key findings

- Constraints on the non-standard interaction parameter ε_{μτ}
- Limits on sterile neutrino model parameters
- Implications for neutrino propagation in matter

## Abstract

We analyze in details the impact of the $10$ $\nu_\tau$ events seen in the OPERA experiment in constraining the Non Standard Interaction parameter $\varepsilon_{\mu\tau}$ affecting neutrino propagation in matter and the allowed parameter space of models with one sterile neutrino of the $3+1$ type.
