摘要
我们报告了利用 XENON100 实验搜寻粒子暗物质的结果，该实验于 2011 年和 2012 年在 Gran Sasso 国家实验室 (LNGS) 运行了 13 个月。XENON100 在感兴趣能区具有 events (kg day keVee) 的超低电磁背景。对 224.6 个有效运行日 34 kg 曝光量的盲分析未发现暗物质相互作用的证据。在预定义的核反冲能区 6.6-30.5 keVnr 中观测到的两个候选事件与 个事件的背景预期一致。使用 6.6-43.3 keVnr 能区的 Profile Likelihood 分析，对质量高于 8 GeV/c 的 WIMP 设定了自旋无关弹性 WIMP-核子散射截面的最严格限制，在 55 GeV/c 处的最小值为 cm（90% 置信水平）。
