The Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS data, accounting for the neutron background, give limits on the spin-independent WIMP-nucleon elastic-scattering cross section that exclude unexplored parameter space above 10 GeV/c2 WIMP mass and, at >75% C.L., the entire 3sigma allowed region for the WIMP signal reported by the DAMA experiment.
低温暗物质搜索（CDMS）实验使用锗和硅探测器，通过弱相互作用大质量粒子（WIMP）与原子核的弹性散射相互作用来寻找它们，同时区分背景粒子的相互作用。考虑到中子本底的CDMS数据，给出了与自旋无关的WIMP-核子弹性散射截面的限制，排除了WIMP质量高于10 GeV/c2的未探索参数空间，并且在大于75%的置信水平下，排除了DAMA实验所报告的WIMP信号的整个3倍标准差允许区域。
