Recent lattice measurements have given accurate estimates of the light and strange quark condensates in the proton. We use these new results to signi cantly improve the dark matter predictions in a set of benchmark models that represent di erent scenarios in the constrained minimal supersymmetric standard model (CMSSM). Because the predicted cross sections are at least an order of magnitude smaller than previously suggested, our results have signi cant consequences for dark matter searches.
