Investigation of the KF-type Lorentz-symmetry breaking gauge models with vortexlike 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 sub( mu [nu] Kappa [lambda]) term. We adopt a particular decomposition of this term in four vectors, and carry out a detailed analysis of causality and unitarity...

Description
Summary:For the CPT-even case of the minimal Standard Model extension, the spin-projector method is adopted to account for the breaking (tensor) K sub( mu [nu] Kappa [lambda]) term. We adopt a particular decomposition of this term in four vectors, 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 sub( mu [nu] Kappa [lambda]) and vortex formation is also investigated in different situations.
