The usual R parity, i.e. R = ( − ) 3 B + L +2 $^{j}$, can be defined for this nonsupersymmetric model so that both n and Φ 1 are odd together with W ± $_{R}$. The lightest n is thus a viable dark-matter candidate (scotino). Here we explore the phenomenology associated with the SU (2)$_{R}$ gauge group of this model, which allows it to appear at the TeV energy scale. The exciting possibility of Z ′ → 8 charged leptons is discussed. The nonsupersymmetric dark left-right model (DLRM) proposed recently [1] is a variant of a supersymmetric left-right extension of the standard model (SM) of particle interactions based on E 6 and inspired by string theory some 23 years ago [2, 3].
