Descrição teórica e fenomenológica da eletrodinâmica violando a Invariância de Lorentz com operadores de altas ordens derivativas.

Abstract

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.
