The LUX-ZEPLIN dark matter search aims to achieve a sensitivity to the WIMP-nucleon spin-independent cross-section down to (1-2) $\times$ $10^{-12}$ pb at a WIMP mass of 40 GeV/$c^2$. This paper describes the simulations framework that, along with radioactivity measurements, was used to support this projection, and also to provide mock data for validating reconstruction and analysis software. Of particular note are the event generators, which allow us to model the background radiation, and the detector response physics used in the production of raw signals, which can be converted into digitized waveforms similar to data from the operational detector. Inclusion of the detector response allows us to process simulated data using the same analysis routines as developed to process the experimental data.

LUX-ZEPLIN (LZ) 暗物质实验的事件模拟

LUX-ZEPLIN 暗物质搜索旨在在 WIMP 质量为 40 GeV/时实现对 WIMP 核子自旋无关截面的灵敏度低至 (1-2) $\times$ $10^{-12}$ pb $c^2$。本文描述了模拟框架,该框架与放射性测量一起用于支持该预测,并为验证重建和分析软件提供模拟数据。特别值得注意的是事件发生器,它允许我们对背景辐射进行建模,以及用于产生原始信号的探测器响应物理,可以将其转换为类似于来自操作探测器的数据的数字化波形。包含探测器响应使我们能够使用与为处理实验数据而开发的相同分析程序来处理模拟数据。
