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…
Remarks on the algebraic structure of (2, 2) double forms
E. Goulart, J. E. Ottoni
We study the algebraic features of covariant tensors of valence four containing two blocks of skew indices. After a rather general treatment, we specialize ourselves to four-dimens…
From disformal electrodynamics to exotic spacetime singularities
Eduardo Bittencourt, Ricardo Fernandes, Érico Goulart +1
We study different types of spacetime singularities which emerge in the context of disformal electrodynamics. The latter is characterized by transformations of the background metri…
Towards a unified description of knotted light
E. Goulart, J. E. Ottoni
Several complementary approaches to investigate knotted solutions of Maxwell's equations in vacuum are now available in literature. However, only partial results towards a unified…
Supergravity corrections to the factor by Implicit Regularization
J. E. Ottoni, A. P. Baeta Scarpelli, Marcos Sampaio +1
We apply Implicit regularization in the calculation of the one-loop graviton and gravitino corrections to the anomalous magnetic moment of the lepton in unbroken supergravity, whic…
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…
