美国地下暗物质实验发现暗物质初步线索

Super-CDMS researchers report possible evidence of WIMPs

继本月初丁肇中团队公布阿尔法磁谱仪项目首批研究暗物质成果后，美国明尼苏达州的地下暗物质实验——超级低温暗物质搜寻计划（Super-CDMS）日前报告了3个疑似暗物质事例．计算结果表明其是大质量弱相互作用粒子（WIMP）的可能性为99.81％．不足5西格玛水平．并不会作为暗物质证据进行发布。

Researchers working at the Super Cryogenic Dark Matter Search （CDMS） facility, located underground in Minnesota＇s Soudan Mine, are reporting in a paper uploaded to the preprint server arXiv that they＇ve found three events that lie in the signal range of Weakly Interacting Massive Particles （WIMPs）. The group also gave a talk detailing their results to an audience at this year＇s American Physical Society meeting-as part of that discussion, they made it clear the noted events do not rise to the level of discovery, nor do they imply the team has found evidence of the existence of dark matter.
