Abstract: In an SU(2)R extension of the standard model, it is shown how the neutral fermion N in the doublet (N,e)R may be assigned baryon number B=1 , in contrast to its SU(2)L counterpart ν in the doublet (ν,e)L which has lepton number L=1 . This baryon-lepton duplicity allows a scalar σ which couples to NLNL to be long-lived dark matter.
