Abstract
A gauge model based on an SU(2)×U(1)×U(1) group is proposed to accommodate a quark-lepton correspondence in neutral current interactions as well as charged current interactions. It predicts a new type of neutral current for neutrino scattering: I(3)-2sin2θQ(ω), where Q(ω)=1/2 or -1/2. On the basis of a composite substructure of quarks and leptons suggested by the quark-lepton correspondence, a new charge Q(ω) can be understood as an electric charge of “fermion” which forms quarks and leptons together with another “boson” carrying the baryon (lepton) number.Keywords
