Resumo:
In this work, we consider electrodynamics violating the Lorentz symmetry with dimension
5 operators. We study with theorists, with modifications in the units: equation of motion,
Maxwell’s equations, dispersion relations and Feynman propagator. We also studied the
phenomenological tests of the Lorentz symmetry violation, which are available in the
electronic version of the GRB041219A gamma rays, for which a high degree of polarization
is observed in the emission of photons. In addition, as a collaboration of the property
model, we investigated the Myers-Pospelov term electromagnetic radiation-induced loop.
The calculation is performed without a fermionic sector where there is interaction with
the background electromagnetic field. One research takes into account how Feynman’s
modified rules and the dimensional regularization scheme.
