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

High Energy Physics - Phenomenology 2010-04-22 v1

Abstract

In the recently proposed dark left-right gauge model of particle interactions, the left-handed fermion doublet (ν,e)L(\nu,e)_L is connected to its right-handed counterpart (n,e)R(n,e)_R through a scalar bidoublet, but νL\nu_L couples to nRn_R only through ϕ10\phi_1^0 which has no vacuum expectation value. The usual R parity, i.e. R=()3B+L+2jR = (-)^{3B+L+2j}, can be defined for this nonsupersymmetric model so that both nn and Φ1\Phi_1 are odd together with WR±W_R^\pm. The lightest nn is thus a viable dark-matter candidate (scotino). Here we explore the phenomenology associated with the SU(2)RSU(2)_R gauge group of this model, which allows it to appear at the TeV energy scale. The exciting possibility of Z8Z' \to 8 charged leptons is discussed.
