Two-loop renormalization of the CPT-even Lorentz-violating Scalar QED
L. C. T. Brito, J. C. C. Felipe, A. C. Lehum +1
Investigating quantum effects arising from high loops in perturbation theory is crucial for the physical applications of any quantum field theory. This paper presents a comprehensi…
Perturbative Aspects of CPT-Even Lorentz-Violating Scalar Chromodynamics
B. Altschul, L. C. T. Brito, J. C. C. Felipe +3
In this work, we formulate the theory of Lorentz-violating scalar Quantum Chromodynamics with an arbitrary non-Abelian gauge group. This theory belongs to the class of models encom…
On the nonlinear electrodynamics in a Lorentz-breaking scenario
E. Neres Júnior, J. C. C. Felipe, A. P. Baêta Scarpelli
In this work, we study a model in nonlinear electrodynamics in the presence of a CPT-even term that violates Lorentz symmetry. The Lorentz-breaking vector, in addition to the usual…
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…
