Superluminal Neutrinos from Gauge Field

TL;DR

This paper proposes that neutrinos could appear superluminal due to a local gauge field effect sourced by the Earth, altering their effective metric and explaining experimental observations.

Contribution

It introduces a gauge field mechanism that modifies neutrino propagation, providing a novel explanation for superluminal neutrino results.

Findings

Neutrino superluminality can be explained by a local gauge field effect.

The model accounts for differences between CERN and SN1987A neutrino observations.

The gauge field coupling effectively changes the background metric for neutrinos.

Abstract

We consider a possibility that the recent OPERA results on neutrinos' superluminality could be caused by a local effect of a new gauge field sourced by the earth. If neutrinos couple to this gauge field via a gauge-invariant but non-renormalizable interaction, the coupling effectively changes a background metric, thereby leading to superluminality of neutrinos. This possibility naturally might explain why neutrinos from CERN CNGS beam to Gran Sasso Laboratory become superluminal while those from SN1987A to Earth become subluminal.
