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…
Propagation features of Lorentz-violating electrodynamics
E. Goulart, J. E. Ottoni, J. C. C. Felipe
This paper explores some propagation features of electrodynamics in a Lorentz-violating scenario, focusing on a specific CPT-even term within the photon sector of the Standard Mode…
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…
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…
Exact Foldy-Wouthuysen transformation for a Dirac equation describing the interaction of spin-1/2 relativistic particles with an external electromagnetic field
Bruno Gonçalves, Mário M. Dias Júnior, Larissa F. Eleotério
The Thomas-Bargmann-Michel-Telegdi (T-BMT) equation is derived using the Exact Foldy-Wouthuysen transformation. Extra new terms were found, and we discuss their possible physical a…
The Schwinger and Chiral Schwinger Models in a Non-perturbative Spectral Regularization
L. F. Eleotério, G. A. Oliveira, E. W. Dias +2
We investigate the employment of a non-perturbative regularization scheme -- the spectral regularization, which is based on the gauge technique, previously implemented in the conte…
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…
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…
Supergraph Approach in a Higher-order LDE Calculation of the Effective Potential for F-type Broken SUSY
M. C. B. Abdalla, R. L. S. Farias, J. A. Helayël-Neto +2
In this work, we adopt the simplest model that spontaneously breaks supersymmetry, namely, the minimal O'Raifeartaigh model. The effective potential is computed in the framework of…
Momentum Space Regularizations and the Indeterminacy in the Schwinger Model
C. W. Morais, A. L. Mota
We revisited the problem of the presence of finite indeterminacies that appear in the calculations of a Quantum Field Theory. We investigate the occurrence of undetermined mathemat…
Axial Vector Coupling and Chiral Anomaly in the Spectral Quark Model
L. C. Ferreira, A. L. Mota
We studied the Adler-Bardeen-Bell-Jackiw anomaly in the context of a finite chiral quark model known as the Spectral Quark Model. Within this model, we obtain the general non-local…
