Some light on "Measurement of the neutrino velocity with the OPERA detector in the CNGS beam"

TL;DR

This paper analyzes the OPERA neutrino velocity measurement, demonstrating that the observed pulse broadening aligns with classical relativity, and clarifies the interpretation of the experimental results.

Contribution

It provides an analysis of pulse broadening effects in the OPERA experiment, supporting the consistency of neutrino velocity measurements with relativity.

Findings

Pulse broadening explains the OPERA results

Results are consistent with classical relativity

No superluminal neutrino velocity detected

Abstract

The recent publication in ArXiv of "Measurement of the neutrino velocity with the OPERA detector in the CNGS beam" has attracted many interest due to the possible theoretical or phenomenological interpretation of the results. A subtle broadening effect on the size of the neutrino pulse appearing in the OPERA measurements is analyzed in this paper to show that the results are in agreement with "classical" theory of relativity.
