CDMS和EDELWEISS的合作结合了他们使用低温锗探测器直接搜索暗物质的结果。总数据集代表614 kg·天当量暴露。在实验之间交换数据之前，选择了一种简单的组合方法。结果解释的限制自旋无关的弱相互作用，大质量粒子（WIMP）的核子截面。对于质量为90 GeV/c^2的WIMP，这种分析是最灵敏的，在90% C. L时，3.3×10^（-44）cm ^2的截面被排除在外。在更高的WIMP质量下，这种组合使单个极限提高了1.6倍，高于700 GeV/c^2。结合数据的替代方法为WIMP质量的某些范围提供了更强的约束，而为其他范围提供了更弱的约束。
The CDMS and EDELWEISS collaborations have combined the results of their direct searches for dark matter using cryogenic germanium detectors. The total data set represents 614 kg·days equivalent exposure. A straightforward method of combination was chosen for its simplicity before data were exchanged between experiments. The results are interpreted in terms of limits on spin-independent weakly interacting, massive particle (WIMP)-nucleon cross section. For a WIMP mass of 90 GeV/c^2, where this analysis is most sensitive, a cross section of 3.3×10^(-44) cm^2 is excluded at 90% C.L. At higher WIMP masses, the combination improves the individual limits, by a factor 1.6 above 700 GeV/c^2. Alternative methods of combining the data provide stronger constraints for some ranges of WIMP masses and weaker constraints for others.
