Axion-Photon Interaction from Nonminimal Dimension-5 Lorentz-Violating Operators
A. J. G. Carvalho, A. G. Dias, A. F. Ferrari +3
In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving o…
Renormalization in Nonminimal Lorentz-Violating Field Theory
J. R. Nascimento, A. Yu. Petrov, C. M. Reyes
We provide the first step towards renormalization in a nonminimal Lorentz-violating model consisting of normal scalars and modified fermions with mass dimension five operators. We…
Higher-order one-loop contributions in Lorentz-breaking QED
A. P. Baeta Scarpelli, L. C. T. Brito, J. C. C. Felipe +2
We calculate higher-order quantum contributions in different Lorentz-violating parameters to the gauge sector of the extended QED. As a result of this one-loop calculation, some te…
Lorentz violation in the linearized gravity
A. F. Ferrari, A. Yu. Petrov
We study some consequences of the introduction of a Lorentz-violating modification term in the linearized gravity, which leads to modified dispersion relations for gravitational wa…
On the aether-like Lorentz-breaking action for the electromagnetic field
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We study the generation of aether-like Lorentz-breaking actions in three, four and five dimensions via an appropriate Lorentz-breaking coupling of electromagnetic and spinor fields…
Five-Dimensional QED, Muon Pair Production and Correction to the Coulomb Potential
J. R. Nascimento, C. A de S. Pires, R. F. Ribeiro
We consider QED in five dimensions in a configuration where matter is localized on a 3-brane while foton propagates in the bulk. The idea is to investigate the effects of the Kaluz…
