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…
Implicit regularization beyond one loop order: scalar field theories
C. R. Pontes, A. P. Baeta Scarpelli, Marcos Sampaio +1
Implicit regularization (IR) has been shown as an useful momentum space tool for perturbative calculations in dimension specific theories, such as chiral gauge, topological and sup…
Arbitrary parameters in implicit regularization and democracy within perturbative description of 2-dimensional gravitational anomalies
Leonardo A. M. Souza, Marcos Sampaio, M. C. Nemes
We show that the Implicit Regularization Technique is useful to display quantum symmetry breaking in a complete regularization independent fashion. Arbitrary parameters are express…
Implicit Regularization and Renormalization of QCD
M. D. Sampaio, A. P. B. Scarpelli, J. E. Ottoni +1
We apply the Implicit Regularization Technique (IR) in a non-abelian gauge theory. We show that IR preserves gauge symmetry as encoded in relations between the renormalizations con…
