Unitarity in Stückelberg electrodynamics modified by a Carroll-Field-Jackiw term
In this work we focus on the Carroll-Field-Jackiw (CFJ) modified electrodynamics in combination with a CPT-even Lorentz-violating contribution. We add a photon mass term to the Lagrange density and study the question whether this contribution can render the theory unitary at tree-level. The analysis...
