A mapping between Lorentz-violating and conventional electrodynamics

A mapping between Lorentz-violating and conventional electrodynamics

The Chern-Simons-type term in the photon sector of the Lorentz-and CPT-breaking minimal Standard-Model Extension (mSME) is considered. It is argued that under certain circumstances this term can be removed from the mSME. In particular, it is demonstrated that for lightlike Lorentz violation a field redefinition exists that maps the on-shell free Chern-Simons model to conventional on-shell free electrodynamics. A compact explicit expression for an operator implementing such a mapping is constructed. This expression establishes that the field redefinition is non-local.
