Covariant Photon Quantization in the SME
arXiv:1309.5890 · doi:10.1142/9789814566438_0032
Abstract
The Gupta Bleuler quantization procedure is applied to the SME photon sector. A direct application of the method to the massless case fails due to an unavoidable incompleteness in the polarization states. A mass term can be included into the photon lagrangian to rescue the quantization procedure and maintain covariance.
