Abstract.
By invoking the existence of a general O(2) symmetry, a minimal left-right symmetric model based on the gauge group \(G = SU(2)_{\mathrm {L}}\otimes SU(2)_{\mathrm {R}}\otimes U(1)_{B-L}\) is shown to require the existence of only two physical Higgs bosons. The lighter Higgs is predicted to have a small mass which could be evaluated by standard perturbation theory. The fermionic mass matrices are recovered by insertion of ad hoc fermion-Higgs interactions. The model is shown to be undistinguishable from the standard model at the currently reachable energies.
