摘要
我们报告了使用 XENONnT 实验进行的首次以弱相互作用大质量粒子（WIMPs）形式存在的暗物质核反冲搜寻，该实验基于一个灵敏液氙质量为 t 的双相时间投影室。在此次搜寻所用的约 1.1 吨·年曝光中，液体靶中的本底 Kr 与 Rn 浓度被降至前所未有的低水平，使得感兴趣区域内的电子反冲本底率为 。对能量介于 keV 与 keV 之间的核反冲事件进行的盲分析未发现显著超出。这导致在 置信度下，对质量为 的 WIMP，其自旋无关 WIMP-核子截面的极小上限为 。同时也给出了自旋相关相互作用的限制。此处分析的全部 WIMP 质量范围内的限制与灵敏度均优于此前 XENON1T 实验在相同曝光下所得结果。
