Baryon-Lepton Duplicity as the Progenitor of Long-Lived Dark Matter

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 $\nu$ in the doublet $(\nu ,e{)}_L$ which has lepton number $L=1$. This baryon-lepton duplicity allows a scalar $\sigma$ which couples to $N_L{N}_L$ to be long-lived dark matter.
