Kaluza-Klein Dark Matter: Direct Detection vis-a-vis LHC (2013 update)

Understand

We present updated results on the complementarity between high-energy colliders and dark matter direct detection experiments in the context of Universal Extra Dimensions (UED).

• In models with relatively small mass splittings between the dark matter candidate and the rest of the (colored) spectrum, the collider sensitivity is diminished, but direct detection rates are enhanced.
• UED provide a natural framework to study such mass degeneracies.
• We discuss the detection prospects for the KK photon $\gamma_1$ and the KK $Z$-boson $Z_1$, combining the expected LHC reach with cosmological constraints from WMAP/Planck, and the sensitivity of current or planned direct detection experiments.
