Classical investigations in a CPT-even Lorentz-violating model and their implications for the Compton effect
E. Neres Júnior, J. C. C. Felipe, A. P. Baêta Scarpelli +2
In this work, we investigate some aspects of the Maxwell electrodynamics with the additive Lorentz-violating (LV) CPT-even term. For this model, we derive the energy and momentum c…
Gauge symmetry and radiatively induced terms in dimension-5 non-minimal Lorentz-violating QED
A. P. B. Scarpelli, A. R. Vieira
In this work, we derive the conditions that assure gauge invariance of a non-minimal dimension-5 Lorentz-violating QED. The two and three point functions at one-loop are computed.…
The full Lorentz-violating vacuum polarization tensor: low and high energy limits
J. C. C. Felipe, A. Yu. Petrov, A. P. Baêta Scarpelli +1
We compute the full vacuum polarization tensor in the fermion sector of Lorentz-violating QED. Even if we assume momentum routing invariance of the Feynman diagrams, it is not poss…
Calculations in Lorentz-breaking scalar QED
Jean C. C. Felipe, A. Yu Petrov, A. P. B. Scarpelli +1
We purpose a study a Lorentz-breaking extension of the scalar QED. We calculate the contributions in the Lorentz-violating parameters to the two-point functions of scalar and gauge…
Gauge embedding procedure: classical and quantum equivalence between dual models
B. Alves Marques, B. Z. Felippe, A. P. Baeta Scarpelli +2
In this paper the gauge embedding procedure of dualization is reassessed through a deeper analysis of the mutual equivalence of vector field models of more generic forms, explicitl…
Advances towards the systematization of calculations with Implicit Regularization
B. Z. Felippe, A. P. Baêta Scarpelli, A. R. Vieira +1
There is currently a high demand for theoretical predictions for processes at next-to-next-to-leading order (NNLO) and beyond, mainly due to the large amount of data which has alre…
