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.

这场竞赛是为了第一次直接探测到暗物质(DM)，它占宇宙质量的85%。LUX-ZEPLIN(LZ)实验是美国/英国DM的旗舰项目，将成为有史以来建造的最大和最先进的直接检测仪器。经过多年的设计和建造，LZ探测器即将在它的新家开始采集数据，它位于美国南达科他州桑福德地下研究设施(SURF)地下一英里处。在这个项目中，我们将分析来自即将到来的LZ科学运行的数据，以探索重要的新参数空间，以发现WIMP暗物质和超越标准模型(BSM)的物理的星系特征。为此，将开发多模式背景模型以及必要的信号模型和与数据进行比较所需的LZ统计工具的扩展。该项目将包括延长前往SURF的行程，以运行和校准LZ探测器。该项目还将包括研发工作的一个重要组成部分，开发无线电分析技术，进行下一代第三代方向探测实验的设计研究，以及应用量子技术作为直接探测暗物质的工具。
