A different interpretation of "Measuring propagation speed of Coulomb fields" by R. de Sangro, G. Finocchiaro, P. Patteri, M. Piccolo, G. Pizzella

TL;DR

This paper challenges previous claims by arguing that measurements do not support the idea that Coulomb fields propagate rigidly with moving charges, emphasizing the importance of acceleration-dependent fields.

Contribution

It provides a reinterpretation of earlier experimental results, clarifying that observed signals relate to acceleration-dependent fields rather than rigid propagation.

Findings

Measurements do not confirm rigid propagation of Coulomb fields.

The observed signals are linked to acceleration-dependent components.

Previous interpretations of the data are reconsidered.

Abstract

We claim that the anti-relativistic statement in de Sangro et al., Eur. Phys. J. C 75, 137 (2015) that the Coulomb field of a moving charge propagates rigidly with it, cannot as a matter of fact be inferred from the measurements reported in that reference. Registered is not the passing of the Coulomb disk, but the acceleration-dependent part of the Lienard-Wiechert field.
