An alternative left–right model of quarks and leptons, where the lepton doublet is replaced with so that is not the Dirac mass partner of , has been known since 1987. Previous versions assumed a global symmetry to allow n to be identified as a dark-matter fermion. We propose here a gauge extension by the addition of extra fermions to render the model free of gauge anomalies, and just one singlet scalar to break . This results in two layers of dark matter, one hidden behind the other.
