Systematization of Basic Divergent Integrals in Perturbation Theory and Renormalization Group Functions
L. C. T. Brito, H. G. Fargnoli, A. P. Baêta Scarpelli +2
We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of basic (logarithmically divergent) integrals which need not be evaluated. Only the c…
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…
