Parity anomaly with impurities and the Pauli--Villars subtraction
Ozório Holanda, René Meyer, Dmitri Vassilevich
We calculate the anomalous part of the polarization tensor of Dirac fermions in dimensions in the presence of impurities described by the scattering rate for arbitrary ex…
Gribov horizon in Noncommutative QED
Ozório Holanda, Marcelo S. Guimaraes, Luigi Rosa +1
It is known that Noncommutative QED (NCQED) exhibits Gribov ambiguities in the Landau gauge. These ambiguities are related to zero modes of the Faddeev-Popov operator and arise in…
Some remarks on the spectral functions of the Abelian Higgs Model
D. Dudal, D. M. van Egmond, M. S. Guimaraes +5
We consider the unitary Abelian Higgs model and investigate its spectral functions at one-loop order. This analysis allows to disentangle what is physical and what is not at the le…
Renormalizability of super Yang-Mills theory in Landau gauge with a Stueckelberg-like field
M. A. L. Capri, D. M. van Egmond, M. S. Guimaraes +4
We construct a vector gauge invariant transverse field configuration , consisting of the well-known superfield and of a Stueckelberg-like chiral superfield. The renormaliz…
On a renormalizable class of gauge fixings for the gauge invariant operator
M. A. L. Capri, D. M. van Egmond, G. Peruzzo +5
The dimension two gauge invariant non-local operator , obtained through the minimization of along the gauge orbit, allows to introduce a non-local ga…
Lorentz invariance violation and simultaneous emission of electromagnetic and gravitational waves
E. Passos, M. A. Anacleto, F. A. Brito +3
In this work, we compute some phenomenological bounds for the electromagnetic and massive gravitational high-derivative extensions supposing that it is possible to have an astrophy…
Induction of the higher-derivative Chern-Simons extension in QED
M. A. Anacleto, F. A. Brito, O. B. Holanda +2
We perform the perturbative generation of the higher-derivative Chern-Simons contribution to the effective action in the three-dimensional QED at zero and finite temperature. In th…
Induction of the Lorentz-violating effective actions in quantum electrodynamics
M. A. Anacleto, F. A. Brito, O. Holanda +1
We introduce a Lorentz-symmetry violating extended quantum electrodynamics (QED) which preserves gauge symmetry. The extended fermionic sector can radiatively induce an extended ef…
