Accelerator Constraints on Dark Matter

The relic density of supersymmetric dark matter is calculable in terms of supersymmetric and Standard Model parameters. The discovery of supersymmetric particles and determination of their parameters could well happen at the next generation hadron collider LHC presently under construction at CERN. The accelerator constraints on the SUSY parameter space at the LHC are presented as well as the accuracy with which the density of supersymmetric cold dark matter could be predicted from collider measurements.
