This paper considers an extension of the electroweak gauge interactions from SU(2){sub L} {times} U(1){sub Y} to SU(2){sub L} {times} U(1){sub L} {times} U(1){sub R}. This extension is motivated by the observed structure of the quarks and leptons, i.e., they form left-handed doublets and right-handed singlets eigenstates of electroweak interactions. In this new extension, the U(1){sub R} serves only the right-handed singlet fermions. Consistent with the measurements of the mass of the standard massive neutral boson Z{sub 0} at the SLAC and CERN colliders and the neutral current couplings involving neutrinos and electrons, the additional massive neutral gauge boson can be as light as a few hundred GeV. The model employs the generalized see-saw mechanism to give masses to all the fermions of the theory.
