摘要: When quantization is performed, the photon Lagrangian needs a gauge-fixing term which breaks conformal (Weyl) invariance. This shown to imply in Friedmann (conformally flat) space-time creation of unphysical, unobservable particles lying zero-norm states; no transverse photons are created. The case massive vector field for also physical produced finally discussed and both cases we show structure space states Kugo-Ojima formalism.
