Dark Left-Right Gauge Model: SU(2)_R Phenomenology

Abstract

In the recently proposed dark left-right gauge model of particle interactions, the left-handed fermion doublet $(\nu ,e{)}_L$ is connected to its right-handed counterpart $(n,e{)}_R$ through a scalar bidoublet, but ${\nu }_L$ couples to $n_R$ only through ${\varphi }_1^0$ which has no vacuum expectation value. The usual R parity, i.e. $R=(-{)}^{3B+L+2j}$, can be defined for this nonsupersymmetric model so that both $n$ and ${\Phi }_1$ are odd together with $W_R^{\pm }$. 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 $Z^{\prime }\to 8$ charged leptons is discussed.
