Ambiguities in the generation of CFJ-terms in a QED with dimension-5 operators in one loop

H. G. Fargnoli, J. C. C. Felipe, G. Gazzola

In this paper, we investigate a Lorentz symmetry breaking extension of Quantum Electrodynamics (QED), incorporating 5-dimensional CPT-odd terms at the one-loop level. Employing an…
