# The mass of the photon

@article{Tu2004TheMO, title={The mass of the photon}, author={Liang-Cheng Tu and Jun Luo and George T. Gillies}, journal={Reports on Progress in Physics}, year={2004}, volume={68}, pages={77 - 130} }

Because classical Maxwellian electromagnetism has been one of the cornerstones of physics during the past century, experimental tests of its foundations are always of considerable interest. Within that context, one of the most important efforts of this type has historically been the search for a rest mass of the photon. The effects of a nonzero photon rest mass can be incorporated into electromagnetism straightforwardly through the Proca equations, which are the simplest relativistic…

Efforts to place limits on deviations from canonical formulations of electromagnetism and gravity have probed length scales increasing dramatically over time. Historically, these studies have passed…

special theory of relativity for photons

- Physics

The photon mass is ordinarily assumed to be exactly zero. However, this is merely a theoretical assumption; there is no experimental evidence to indicate that the photon mass is identically zero. In…

Atomic Spectroscopy and the Photon Mass: Effects on the hydrogen ground-state

The photon is the particle that mediates the electromagnetic interaction. This particle appears as a result of the quantization of Maxwell’s theory with the peculiarity that has no mass [12].…

Electric and Magnetic Fields Due to Massive Photons and Their Consequences

The main ideas and methods currently used to obtain upper limits on the photon rest mass from astrophysical data are briefly reviewed. One method is based on the fact that if the photon has nonzero…

Massive electrodynamics and the magnetic monopoles.

- PhysicsPhysical review. D, Particles and fields

Under rather general assumptions it is proved that the construction of such an algebra is not possible and therefore the quantization condition cannot be derived and this points to the conclusion that the Dirac monopole and the finite photon mass cannot coexist within one and the same theory.

Experimental tests of Coulomb's Law and the photon rest mass
