Uncertainties in the Prediction of the Relic Density of Supersymmetric   Dark Matter
  We investigate how well the relic density of dark matter can be predicted in mSUGRA. We determine the parameters to which the relic density is most sensitive and quantify the collider accuracy needed to match the accuracy of WMAP and PLANCK.
