最近的晶格测量给出了质子中夸克凝聚的精确估计。我们使用这些结果显着提高暗物质的预测在基准模型内的约束最小超对称标准模型。预测的自旋无关的横截面至少比以前建议的小一个数量级，我们的结果对暗物质搜索有重大影响。
Recent lattice measurements have given accurate estimates of the quark condensates in the proton. We use these results to significantly improve the dark matter predictions in benchmark models within the constrained minimal supersymmetric standard model. The predicted spin-independent cross sections are at least an order of magnitude smaller than previously suggested and our results have significant consequences for dark matter searches.
