The race is on to make the first direct detection of the Dark Matter (DM) that accounts for 85% of the mass of the Universe. The LUX-ZEPLIN (LZ) experiment is the flagship US/UK DM project that will be the largest and most advanced direct detection instrument ever built. After many years of design and construction the LZ detector is about to start data taking in its new home, a mile underground at the Sanford Underground Research Facility (SURF), South Dakota, USA. In this project, we will analyse data from the forthcoming LZ science runs to explore significant new parameter space towards discovery of WIMP dark matter and galactic signatures of physics beyond the standard model (BSM). To do this a multimodal background model will be developed alongside the necessary signal models and extensions to the LZ statistical tools needed to compare with data. The project will include extended trips to SURF to run and calibrate the LZ detector. The project will also include a significant component of R&D work developing radio-assay techniques and performing design studies towards the next Generation-3 direction detection experiment, and in the application of quantum technologies as a tool for direct detection of dark matter.

该竞赛将首次直接检测到占宇宙质量的85％的暗物质（DM）。 Lux-Zeplin（LZ）实验是US/UK DM项目，它将是有史以来最大，最先进的直接检测工具。经过多年的设计和构建，LZ探测器即将开始在其新家中使用数据，这是美国南达科他州Sanford Underground Research Facility（Surf）的地下一英里。在该项目中，我们将分析即将推出的LZ Science运行的数据，以探索在标准模型（BSM）之外发现WIMP暗物质和物理的银河系特征的重要新参数空间。为此，将开发多模式背景模型，并与必要的信号模型以及与数据进行比较所需的LZ统计工具的扩展。该项目将包括延长的旅行以冲浪以运行和校准LZ检测器。该项目还将包括开发无线电测定技术的研发工作的重要组成部分，并对下一代3方向检测实验进行设计研究，以及应用量子技术作为直接检测暗物质的工具。
