摘要
XENON 合作组已发布了基于暗物质在液氙探测器靶上反冲的若干特定暗物质-核子反冲谱的严格限制。本文中，我们提出一种适用于任意核反冲谱的 XENON1T 1 吨·年核反冲搜寻的近似似然。随本文一并发布用于按我们所提方法计算上限的数据和代码。该近似似然在重建能量区间内构建，并沿各区间信号期望值进行剖面。该方法可用于计算任意核反冲谱的近似似然，从而得出大多数统计结果。使用该方法计算近似结果比 XENON1T 原始发表中用于特定反冲谱族设定限制的似然快约三个数量级。使用相同方法，我们给出了即将开展的 XENONnT 实验的基于玩具蒙特卡洛模拟的区间似然，同样可用于评估其最终 20 吨·年曝光中对任意核反冲特征的灵敏度。
