| Abstract: | The U1 × U1(loc) × SU2(loc) invariant Weinberg lagrangian can be reduced to a U1 × SU2(loc) invariant lagrangian without hypercharge group involving only a single left-handed Weyl spinor field and an isotriplet gauge vector field. Spontaneous symmetry breakdown is induced by condensation of fermion pairs. Charge appears simply as “isospin charge”. |
