Modified Euler-Heisenberg effective action and Proper-Time Method in Lorentz-Violating Scalar QED
L. C. T. Brito, J. C. C. Felipe, A. C. Lehum +2
Quantum photon effects in vacuum provide an interesting setting to test quantum electrodynamics, serving as a source for predictions about physics beyond the Standard Model. In thi…

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…
