Identification of Dark Matter particles with LHC and direct detection data

Understand

Dark matter (DM) is currently searched for with a variety of detection strategies.

• Accelerator searches are particularly promising, but even if Weakly Interacting Massive Particles (WIMPs) are found at the Large Hadron Collider (LHC), it will be difficult to prove that they constitute the bulk of the DM in the Universe.
• We show that a significantly better reconstruction of the DM properties can be obtained with a combined analysis of LHC and direct detection (DD) data, by making a simple Ansatz on the WIMP local density, i.e.
• by assuming that the local density scales with the cosmological relic abundance.
