Gauge invariance and the CPT and Lorentz violating induced Chern-Simons-like term in extended QED
A. P. Baeta Scarpelli, Marcos Sampaio, M. C. Nemes +1
The radiative induction of the CPT and Lorentz violating Chern-Simons (CS) term is reassessed. The massless and massive models are studied. Special attention is given to the preser…
Implicit regularization beyond one loop order: gauge field theories
E. W. Dias, A. P. Baeta Scarpelli, L. C. T. Brito +2
We extend a constrained version of Implicit Regularization (CIR) beyond one loop order for gauge field theories. In this framework, the ultraviolet content of the model is displaye…
On the equivalence between Implicit Regularization and Constrained Differential Renormalization
Carlos R. Pontes, A. P. Baêta Scarpelli, Marcos Sampaio +2
Constrained Differential Renormalization (CDR) and the constrained version of Implicit Regularization (IR) are two regularization independent techniques that do not rely on dimensi…
Mass Scales and Their Relations in Symmetric Quantum Field Theory
S. R. Gobira, M. C. Nemes
We illustrate the importance of mass scales and their relation in the specific case of the linear sigma model within the context of its one loop Ward identities. In the calculation…
Renormalization Conditions and the Sliding Scale in the Implicit Regularization Scheme: A Simple Connection
A. Brizola, S. R. Gobira, Marcos Sampaio +1
We describe in detail how a sliding scale is introduced in the renormalization of a QFT according to integer-dimensional implicit regularization scheme. We show that since no regul…
N-loop Treatment of Overlapping Diagrams by the Implicit Regularization Technique
S. R. Gobira, M. C. Nemes
We show how the Implicit Regularization Technique (IRT) can be used for the perturbative renormalization of a simple field theoretical model, generally used as a test theory for ne…
