Dark Matter and BSM Physics with the LUX-ZEPLIN experiment and R&D for a future rare-event observatory

首次直接探测到占宇宙质量85%的暗物质（DM）的竞赛已经开始。LUX-ZEPLIN （LZ）实验是美国/英国DM项目的旗舰项目，它将是有史以来建造的最大和最先进的直接探测仪器。经过多年的设计和建造，LZ探测器即将在其位于美国南达科他州桑福德地下研究设施（SURF）地下一英里的新家开始数据采集。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）的物理星系特征。为此，将开发一个多模态背景模型，以及必要的信号模型和LZ统计工具的扩展，以便与数据进行比较。该项目将包括延长到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，即开发无线电分析技术，对下一代第三代方向探测实验进行设计研究，以及应用量子技术作为直接探测暗物质的工具。

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.
