Testing the Special Relativity Theory with Neutrino interactions

TL;DR

This paper reinterprets neutrino detection data to set stringent limits on violations of special relativity, focusing on neutrino velocity and energy loss predictions from the OPERA experiment.

Contribution

It provides new bounds on special relativity violations by analyzing NOMAD detector data for neutrino interactions, based on recent neutrino velocity measurements.

Findings

Stringent limits on neutrino velocity deviations from light speed.

Constraints on energy loss mechanisms for superluminal neutrinos.

Reinterpretation of NOMAD data enhances tests of fundamental physics.

Abstract

A recent measurement of neutrino velocity by the OPERA experiment and prediction of energy loss of superluminal neutrino via the pair creation process $\nu\to \nu e^+e^-$ stimulated a search of isolated $e^+e^-$ pairs in detectors with good tracking capability traversed by a large flux of high energy neutrino like NOMAD. NOMAD has already searched for similar topologies. These results can be reinterpreted to provide stringent limits on special relativity violating parameters separately for each $\nu$ species.
