We emphasize the stabilizing symmetry for dark matter does not have to be the commonly used parity symmetry. In this talk, we examine the potential of the CERN Large Hadron Collider to distinguish models with parity stabilized dark matter from models in which the dark matter is stabilized by other symmetries. We will present signals involving the decays of mother particles into dark matter and Standard Model particles. Novel reconstruction techniques for these scenarios are shown. As well, we will also examine signals involving final states of long lived visible particles with dark matter.
