The OPERA neutrino velocity result and the synchronisation of clocks

TL;DR

The paper critiques the OPERA experiment's claim of superluminal neutrinos, emphasizing that clock synchronization conventions in rotating frames may invalidate their faster-than-light velocity interpretation.

Contribution

It highlights the importance of clock synchronization conventions in one-way speed measurements and questions the validity of the OPERA results due to these factors.

Findings

Synchronization conventions can affect one-way speed measurements.

The OPERA analysis may not have properly accounted for synchronization effects.

Superluminal neutrino claims could be invalidated by synchronization issues.

Abstract

The CERN-OPERA experiment claims to have measured a one-way speed of neutrinos that is apparently faster than the speed of light c. One-way speed measurements such as these inevitably require a convention for the synchronisation of clocks in non-inertial frames since the Earth is rotating. We argue that the effect of the synchronisation convention is not properly taken into account in the OPERA analysis and may well invalidate their interpretation of superluminal neutrino velocity.
