Distinguishing Dark Matter Stabilization Symmetries Using Multiple Kinematic Edges and Cusps

Understand

We emphasize that the stabilizing symmetry for dark matter (DM) particles does not have to be the commonly used parity (Z_2) symmetry.

• We therefore examine the potential of the colliders to distinguish models with parity stabilized DM from models in which the DM is stabilized by other symmetries.
• We often take the latter to be a Z_3 symmetry for illustration.
• We focus on signatures where a single particle, charged under the DM stabilization symmetry decays into the DM and Standard Model (SM) particles.
