摘要
我们报告了 XENON1T 的首次暗物质搜寻结果，XENON1T 是一个靶质量约 2000 kg 的双相（液-气）氙时间投影室，在意大利的 Laboratori Nazionali del Gran Sasso 运行，也是首个此类吨级探测器。盲法搜寻使用了 2016 年 11 月至 2017 年 1 月期间采集的 34.2 个有效天的数据。在 (104212) kg 的有效质量内，以及在 WIMP 暗物质搜寻感兴趣的 [5, 40] 能量范围内，电子反冲背景为 events/(kg day )，这是暗物质探测器中有史以来达到的最低值。轮廓似然分析表明，数据与仅背景假设一致。我们推导出了 WIMP 质量大于 10 GeV/c 时自旋无关 WIMP-核子相互作用截面的最严格排除极限，在 90% 置信水平下，对于 35-GeV/c 的 WIMP，最小值为 7.7 cm。
