ON MASSIVE AND MASSLESS PHOTONS,

Abstract

The vanishing of the longitudinal mode of a massive photon as the photon mass goes to zero in gauge-invariant electrodynamics is investigated with the help of examples. A distinction between two forms of gauge-invariant amplitudes is made in order to clarify this limit; conditions are then obtained so that the limiting process is smooth. From these conditions results on the equality of particle charge which are usually derived by means of Ward's identity can be obtained. (Author)
