Perturbative Analysis of CPT-Odd Lorentz-Violating Scalar QCD
J. C. C. Felipe, L. C. T. Brito, A. C. Lehum +2
We perform a complete one-loop renormalization analysis of CPT-odd Lorentz-violating scalar quantum chromodynamics with adjoint scalar matter. Working to first order in the preferr…
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…
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…
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…
Three- and Four-Point Functions in CPT-Even Lorentz-Violating Scalar QED
B. Altschul, L. C. T. Brito, J. C. C. Felipe +3
The renormalization of quantum field theories usually assumes Lorentz and gauge symmetries, besides the general restrictions imposed by unitarity and causality. However, the set of…
