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.

实验粒子和天体粒子物理(EPAP)小组的目的是通过研究基本粒子的性质来解决我们对物质理解中的一些主要开放问题。特别是，我们的目标是解决暗物质和中微子领域的许多悬而未决的问题。我们还在继续寻找新的物理学，解决包括暗物质和引力波在内的来自天体物理源的现象。LZ实验最近发布了其首次科学运行(SR1)的世界领先的WIMP搜索结果，仅使用了60天的实时数据。在广泛的运行前校准和探测器维护期之后，LZ即将为剩余的科学运行(SR2+)进入稳定状态操作，以期在2025/26年前完成1,000次实时照射。这一授权期涵盖了LZ开发阶段的大部分时间，在这一阶段，LZ将为WIMP和其他动机良好的热遗迹DM候选者探索重要的新参数空间。高能天体物理中微子的物理在不久的将来具有非常高的发现潜力。自2013年首次观测以来，冰立方已经对天体物理中微子进行了一系列观测，包括天空图、能谱和风味结构。我们将致力于中微子味道的测量，并使用中能启动事件样本产生最先进的天体物理中微子味道测量。我们还在加拿大的SNO+实验中发挥重要作用，该实验将收集其主要数据，以寻找无中微子的双β衰变，从而探索中微子的性质和质量，在此授权期内。我们的工作将通过分析协调以及对时间相关背景和探测器响应的仔细研究，使这一测量和其他关键测量(例如进一步探测振荡参数的太阳和反应堆中微子光谱)成为可能。
