An alternative left–right model of quarks and lep-tons, where the SU(2)_R lepton doublet (ν, l)_R is replaced with (n, l)_R so that n_R is not the Dirac mass partner of ν_L, has been known since 1987. Previous versions assumed a global U(1)_S 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 U(1)_S.This results in two layers of dark matter, one hidden behind the other.
