Parity symmetric left-right models provide a viable solution to the strong CP problem. Spontaneous breaking of the Parity symmetric model results in heavy gauge bosons that are searched for at colliders, placing a lower bound on the Parity breaking scale close to 14 TeV. However, without an upper bound, the Parity breaking scale may be as large as the Planck scale. In this talk, I will discuss the minimal Parity symmetric left-right model and show that by embedding a WIMP dark matter candidate one obtains an upper bound on the Parity breaking scale that is far below the Planck scale. I will focus on three well-motivated embeddings of WIMP dark matter and demonstrate how an upper bound on the Parity breaking scale is obtained by requiring that the WIMP obtains the correct relic abundance. I will then discuss current constraints on the free parameters of the model— the Parity breaking scale and WIMP mass-- and motivate future indirect detection experiments such as C.T.A. that can probe the entire parameter space for certain galactic center dark matter density profiles.
