Displaced Vertices from Pseudo-Dirac Dark Matter

Understand

Displaced vertices are relatively unusual signatures for dark matter searches at the LHC.

• We revisit the model of pseudo-Dirac dark matter (pDDM), which can accommodate the correct relic density, evade direct detection constraints, and generically provide observable collider signatures in the form of displaced vertices.
• We use this model as a benchmark to illustrate the general techniques involved in the analysis, the complementarity between monojet and displaced vertex searches, and provide a comprehensive study of the current bounds and prospective reach.
