Perturbative generation of photon Lorentz violating terms from a pseudo-tensor Lorentz-breaking extension of QED

A. J. G. Carvalho, A. F. Ferrari, A. M. de Lima +2

We consider an extended QED with the addition of a dimension-five Lorentz-breaking coupling between spinor and gauge fields, involving a pseudo-tensor ${\kappa }^{\mu \nu \lambda \rho }$. The specific form…
