Abstract
A left-right-symmetric extension of the standard electroweak interaction model is presented in which baryon- (B-) and lepton- (L-) number conservation are considered as spontaneously broken gauge symmetries. The gauge, global, and the mixed gauge-gravitational anomalies in the model are canceled by invoking new fermion matter that carries baryon as well as lepton numbers. We find a class of models in which the exotic fermions carry the same electric charges as the N families of conventional fermions but different B and L charges. The Higgs structure in this case allows a light massive neutral boson with a lower bound of 120 GeV. © 1990 The American Physical Society.
