项目摘要

The Sussex Experimental Particle Physics (EPP) group counts eleven investigators, and focuses on the following main research areas:- the exploration of the Energy Frontier at the ATLAS experiment, ATLAS Upgrades and in future opportunities at colliders; - the exploration of the Intensity Frontier with Neutrino Physics at the SNO+, NOVA, DUNE and SBND experiments;- R&D for new detectors at future experiments;- precision measurements of the neutron electric dipole moment (the nEDM experiment).The group participates in GridPP and Sussex hosts a certified Grid Tier-2 computing cluster.At ATLAS, we search for physics beyond the current understanding of particle physics. We study in detail the particle interactions to verify our current understanding, but also look for evidence of new processes. This includes the search for Dark Matter - the elusive component of the Universe that we know is there from many cosmological experimental results, but that has not yet been observed and is not yet accounted for in our current models describing our understanding of matter. In parallel with the exploitation of ATLAS and the ATLAS upgrade work, we will maintain an involvement in R&D and physics studies for possible future colliders, aiming to further deepen our understanding of matter and the Universe.We also search directly for Dark Matter by building and operating experiments to try and observe Dark Matter interacting directly inside these experiments.The neutrino has already provided some unexpected surprises and its study promises to answer fundamental questions about the nature of matter. At SNO+, we search for rare decays that could reveal the fundamental nature of neutrinos. At NOvA, we hope to better understand the extremely small masses of neutrinos and test whether matter and anti-matter perhaps behave in different ways. This study will be continued at the DUNE (a future, large-scale liquid-argon experiment). The combination of the studies at the SNO+ and DUNE/NOvA experiments has the potential to explain one of science's biggest questions to date: why is the Universe currently made out of matter and why is there no anti-matter any more? There have been some hints that there are more than the three neutrinos that we so far know about. The SBND experiment will look for evidence for new neutrinos and allow us to build up direct experience with the technology for the future DUNE experiment.The nEDM experiment studies the properties of neutrons with exquisite precision, complementing the ATLAS, neutrino and dark matter programmes by looking in a completely different way for evidence of a difference in behaviour between matter and antimatter.We participate in experiments through the analysis of data and contributions to technical deliverables. This builds skills among our PhD students and our researches and these developments have led to strong impact. We will continue to do this, in particular in the area of Artificial Intelligence, exploiting techniques that we use in our research. We will continue to actively interact with local industry and forge stronger links. Furthermore, we will bring our research to schools, teachers and the general public in innovative ways on a local, national and international level

苏塞克斯实验粒子物理（EPP）小组共有11名研究人员，并专注于以下主要研究领域：-在ATLAS实验中探索能量前沿，ATLAS升级和未来在对撞机上的机会; -在SNO+，NOVA，DUNE和SBND实验中探索中微子物理的强度前沿;-在未来实验中研发新探测器;- 中子电偶极矩的精确测量（nEDM实验）。该小组参与了GridPP，Sussex拥有一个经过认证的Grid Tier-2计算集群。在ATLAS，我们寻找超越当前粒子物理学理解的物理学。我们详细研究粒子相互作用，以验证我们目前的理解，但也寻找新过程的证据。这包括寻找暗物质-我们从许多宇宙学实验结果中知道宇宙中难以捉摸的组成部分，但尚未被观察到，并且尚未在我们目前描述我们对物质的理解的模型中解释。在开发ATLAS和升级ATLAS的同时，我们将继续参与未来可能的对撞机的研发和物理研究，旨在进一步加深我们对物质和宇宙的理解。我们还通过建立和运行实验来直接寻找暗物质，试图观察暗物质在这些实验中直接相互作用。中微子已经提供了一些意想不到的惊喜，有望回答关于物质本质的基本问题。在SNO+，我们寻找可以揭示中微子基本性质的罕见衰变。在NOvA，我们希望更好地了解中微子的极小质量，并测试物质和反物质是否可能以不同的方式表现。这项研究将在DUNE（未来的大规模液氩实验）继续进行。SNO+和DUNE/NOvA实验的结合有可能解释迄今为止科学界最大的问题之一：为什么宇宙目前是由物质组成的，为什么不再有反物质？有一些迹象表明，中微子的数量比我们目前所知的三个中微子要多。SBND实验将寻找新中微子的证据，并使我们能够为未来的DUNE实验建立直接的技术经验。nEDM实验以极高的精度研究中子的性质，补充了ATLAS，中微子和暗物质计划，以完全不同的方式寻找物质和反物质之间行为差异的证据。我们通过分析数据和对技术交付成果的贡献。这在我们的博士生和我们的研究中建立了技能，这些发展产生了强烈的影响。我们将继续这样做，特别是在人工智能领域，利用我们在研究中使用的技术。我们将继续积极与本地业界互动，加强联系。此外，我们将把我们的研究，以创新的方式在地方，国家和国际层面的学校，教师和公众
