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.
