About Statistical Questions Involved in the Data Analysis of the OPERA Experiment

TL;DR

This paper critically examines the statistical analysis of the OPERA neutrino experiment, arguing that the data do not conclusively demonstrate superluminal neutrino speeds due to interpretative issues rather than data accuracy.

Contribution

It provides a statistical re-evaluation of OPERA data, highlighting the interpretative challenges that prevent definitive conclusions about superluminal neutrinos.

Findings

Data do not unambiguously support superluminal neutrinos

Statistical constraints limit definitive interpretation

Analysis methods show interpretative issues are key

Abstract

The authors of the OPERA experiment [arXiv:1109.4897] claim that "the measurement indicates an early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum". In this note we analyze the statistical aspects of the experimental results presented in [arXiv:1109.4897], assuming that no hidden experimental bias exists. Due to statistical constraints, we show (through two different methods) that the experimental data presented in [arXiv:1109.4897] do not permit to conclude unambiguously with the existence of a superluminal behavior of neutrinos. The problem lies essentially in the interpretation of the data and not in their veracity.
