暗物质、CMSSM和格点量子色动力学

Dark matter, the CMSSM and lattice QCD

Joel Giedt, Anthony W. Thomas, Ross D. Young

摘要:

最近的晶格测量给出了质子中的光和奇异夸克凝聚的精确估计。我们使用这些新的结果显着提高暗物质的预测在一组基准模型,代表不同的情况下,在约束最小超对称标准模型(CMSSM)。由于预测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要意义。

英文摘要:

Recent lattice measurements have given accurate estimates of the light and strange quark condensates in the proton. We use these new results to significantly improve the dark matter predictions in a set of benchmark models that represent different 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 significant consequences for dark matter searches.
