Description
The parity solution to the strong CP problem, which predicts a $SU(3)_C \times SU(2)_L \times SU(2)_R \times U(1)_X$ gauge group, has been proposed and known for years. This group is spontaneously broken down to the SM gauge group at a parity-breaking scale $v_R$. Though collider searches for heavy gauge bosons have put a lower limit on $v_R$, the upper limit of $v_R$ has not been set and can be much above the reach of collider experiments. In this work, we discuss a few possible WIMP dark matter candidates in the minimal Higgs model. In some of the cases, an upper limit of $v_R$ is set to avoid the bound from dark matter direct detection. The dark matter mass and symmetry-breaking scale can be further probed by direct detection and collider experiments in the near future.
