摘要
LUX-ZEPLIN (LZ) 是下一代暗物质直接探测实验，将在美国南达科他州Lead的Sanford Underground Research Facility (SURF) 地下4850英尺处运行。LZ使用活性质量为7吨的两相氙探测器，主要搜寻与弱相互作用大质量粒子（WIMPs）的低能相互作用，WIMPs被假设构成我们星系晕中的暗物质。本文基于最新的本底估计和探测器模拟，给出了LZ的WIMP预期灵敏度。对于使用5.6吨 fiducial 质量、运行1000 live day 的情况，预计LZ将在90%置信水平排除40 GeV/质量WIMP之上自旋无关WIMP-核子截面大于 cm 的情况。此外，预计 发现潜力将达到低于近期实验排除极限的截面。对于自旋相关WIMP-中子（-质子）散射，预计40 GeV/质量WIMP的灵敏度为 cm（ cm）。随着地下安装顺利进行，LZ将于2020年在SURF进入调试阶段。
