摘要
Ne’eman and Fairlie have recently attempted to embed the SU(2)×U(1) electro-weak group into a supersymmetric SU(2|1) gauge theory. Fairlie and others further extended the graded gauge fields over a space time manifold with more than 4 dimensions. Such an embedding would fix the Weinberg angle to be sin^2θ_ω=1/4 and if it was performed in an extended space time or super space
