Query: An investigation of the $K_{F}$-type Lorentz-Symmetry Breaking Gauge
  Models with Vortex-like Configurations   For the CPT-even case of the minimal Standard Model Extension, the
spin-projector method is adopted to account for the breaking (tensor) $% K_{\mu
\nu \kappa \lambda}$ term. We adopt a particular decomposition of this term in
fourvectors, and carry out a detailed analysis of causality and unitarity. From
this study, we are able to impose conditions on the decomposition of the
$K_{\mu \nu \kappa \lambda}$ and vortex formation is also investigated in
different situations.
