Neutrino dispersion relation changes due to radiative corrections as the origin of faster-than-light-in-vacuum propagation in a medium

TL;DR

This paper explores how radiative corrections to neutrino dispersion relations in nonstandard vacuums could lead to superluminal neutrino speeds, potentially explaining experimental anomalies and observational results.

Contribution

It proposes a theoretical mechanism where radiative corrections alter neutrino dispersion, providing a possible explanation for faster-than-light neutrino observations.

Findings

Radiative corrections can modify neutrino speeds in nonstandard vacuums.

The mechanism may reconcile OPERA results with SN 1987A observations.

Theoretical model supports superluminal neutrino propagation under certain conditions.

Abstract

Radiative corrections to the dispersion of neutrinos in nonstandard vacuum may give rise to "boosts" in their speed. This could explain recent experimental evidence by the OPERA collaboration, as well as the null result indicated by the supernova 1987A (SN 1987A) measurements of neutrino and photon arrival times.
