The LUX-ZEPLIN (LZ) experiment is a next-generation direct detection dark matter (DM) experiment that will become operational in 2020. The aim of this project is to search for interactions of DM particles with Xenon nuclei that lead to scintillation and ionization signals. In order to distinguish these from background processes an accurate simulation of the experiment and the generated signals is required. This project aims at first improving the optical simulation, i.e., the simulation of millions of photons that are produced as a results of a DM - Xenon nucleus interaction, how they propagate through the detector and how they are recorded by large arrays of photomultipliers. This will pave the way for analysing the data collected by LZ to search for signals of dark matter interactions, where focus will be placed on searching for high nuclear recoil signals that would result from recently proposed novel DM interaction models.

LUX-ZEPLIN (LZ) 实验是下一代直接探测暗物质 (DM) 实验，将于 2020 年投入运行。该项目的目的是寻找 DM 粒子与氙核的相互作用，从而产生闪烁和电离信号。为了将这些过程与背景过程区分开来，需要对实验和生成的信号进行精确模拟。该项目的目标首先是改进光学模拟，即模拟由于 DM - 氙核相互作用而产生的数百万个光子、它们如何通过探测器传播以及它们如何被大型光电倍增管阵列记录。这将为分析 LZ 收集的数据以搜索暗物质相互作用的信号铺平道路，其中重点将放在搜索最近提出的新型 DM 相互作用模型产生的高核反冲信号上。
