Abstract

The photon is commonly believed being the only free massless particle. Deviations from the Ampère-Maxwell law, due to a photon mass, real for the de Broglie-Proca theory, or effective for the Lorentz-Poincaré Symmetry Violation (LSV) in the Standard-Model Extension (SME) were sought in six years of MMS satellite data. In a minority of cases (but mostly in the solar wind: 8.6% for the modulus and 16.8% for the Cartesian components for top-quality burst data and best tetrahedron configurations), deviations have been found. After error analysis, the minimum photon mass value would be 1.74×1053 kg while the LSV parameter |kAF| would be 4.95×1011 m1. Future satellite measurements may clarify the nature of these deviations, whether unaccounted errors or profoundly meaningful deviations.
