O estudo do setor de gauge CPT-par do modelo padrão estendido acrescido de um potencial do tipo Higgs e a generalização supersimétrica do tensor Kf

Abstract

The CPT-even gauge sector of the Standard Model Extension (SME) plus a Higgs-like potential is studied. Besides, conditions above (the decomposition used) the Lorentz symmetry violation tensor are imposed in such way that this model can be a consistent quantum eld theory and vortexlike solutions can be investigated. A supersymmetric generalization of the decomposition (of Lorentz symmetry violation tensor) used is made too, promoting the usual decomposition, of a simple ansatz, to a special case of a generalization inferred by supersymmetry arguments
