Abstract

A renormalizable model of weak interactions is presented. The leptons and the SU(3) quarks are classified in an SU(4) × SU(2) symmetry scheme in which the quantum numbers are charge, baryon number, lepton number, and weakness - a quantum number that replaces the usual second lepton number. The coupling of a sextet of spinless bosons to the leptons and hadrons gives a theory of weak interactions that has universality, the correct selection rules, renormalizability, conserved vector current, and VA in the local limit. Elastic eνμ scattering is predicted. The intermediate scalar boson leads to μe and ee pairs in the conventional high-energy neutrino experiments but no μμ pairs are predicted. Some neutral-current effects are expected and these are consistent with present data.
