Abstract:

The SU(2) ⊗U(1) electroweak gauge theory derived out of an SU(2/1) gauge theory is investigated from a point of view that the SU(2/1) symmetry is an underlying supersymmetry realized in internal lines of the Feynman diagrams of an SU(2) ⊗U(1) gauge theory. The action with such an underlying supersymmetry is derived from one for the SU(2/1) symmetry by eliminating ghost fields which are peculiar to the gauge theories of internal supersymmetry. In particular, it is shown that in this theory, the Faddeev-Popov fields coming from the gauge fixing term for fermionic gauge transformations play the role of Higgs-like scalar fields.
