项目摘要

The aim of the Experimental Particle & Astroparticle Physics (EPAP) group is to address some of themajor open questions in our understanding of matter through the study of the nature of fundamentalparticles. In particular, we aim to address many of the open questions in dark matter and neutrino sector. We also continue to search for new physics, addressing phenomena including darkmatter and gravitational waves from astrophysical sources.The LZ experiment recently released world-leading WIMP-search results from its first science run (SR1) using just 60 live days of data. Following an extensive pre-run calibrationand detector maintenance period, LZ is about to enter steady-state operations for the remaining scienceruns (SR2+) towards a complete 1,000 live-day exposure by 2025/26. This grant period covers the majorityof this exploitation phase in which LZ will explore significant new parameter space for both WIMPs andother well-motivated thermal-relic DM candidates.Physics with high-energy astrophysical neutrinos has a very high discovery potential in the near future.Since first observing them in 2013, IceCube has made a series of observations of astrophysical neutrinosincluding sky map, energy spectrum, and flavor structure. We will work on the nutrino flavour measurement and produce the state-of-the-art astrophysicalneutrino flavour measurement using the Medium-Energy Starting Event sample.We also play an important role in the SNO+ experiment in Canada, which will collect its main datato search for neutrino-less double beta decay, hence probing the nature and mass of the neutrino,during this grant period. Our work will enable this and other key measurements (such as solar andreactor neutrino spectra that further probe oscillation parameters) through analysis coordinationand a careful study of time correlated backgrounds and detector response.

实验粒子和天线物理（EPAP）组的目的是通过研究基本粒子的性质来解决我们对物质的一些开放问题。特别是，我们旨在解决暗物质和中微子部门中的许多开放问题。我们还继续寻找新的物理学，以解决来自天体物理学来源的黑暗和引力波在内的现象。LZ实验最近仅使用60个现场直播的数据发布了其首次科学运行（SR1）的世界领先的WIMP搜索结果。在经过广泛的校准和检测器维护期之后，LZ即将进入剩余的Scienceruns（SR2+）的稳态操作，到2025/26到2025/26的全天实时暴露。这项赠款期涵盖了这个剥削阶段的多数，在该阶段中，LZ将探索烟丝和其他充分动机的热电学DM候选物的重要新参数空间。具有高能量天体中微子具有高能量天体中微子的物理学在不久的将来都有很高的发现潜力。频谱和风味结构。我们将使用中等能力的起始事件样本进行Nutrino风味测量，并生产最新的天体物理神经植物风味测量。我们在加拿大的SNO+实验中也起着重要作用，该实验将在本授予期间的性质和质量中，从而收集其主要数据搜索无中微子的无双β衰减，因此可以探讨本质和质量。我们的工作将通过分析协调和仔细研究时间相关的背景和检测器响应进行仔细研究，从而实现这一和其他关键测量值（例如太阳反应器中微子光谱，进一步探测振荡参数）。
