摘要：
The SU(2)XU(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)XU(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.
