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 the neutrino sector. Wealso continue to search for new physics, addressing phenomena including proton decay, ultra-light darkmatter and gravitational waves from astrophyiscal sources.Through our long-standing involvement in the Japanese programme of experiments: T2K,Super-Kamiokande and Hyper-Kamiokande, we work on precision neutrino oscillation measurementscombining both beam and atmospheric neutrino samples, aiming to ultimately understand thecontribution of leptonic CP violation towards explaining the matter-antimatter asymmetry of ouruniverse. To facilitate successful measurements, we are pursuing a detailed understanding ofrelevant neutrino interaction cross-sections (in particular electron neutrino cross-sections),detector response and systematic uncertainties. We also support these efforts by developing thecomputing software infrastructure required to analyse the large data volumes and maintaining theouter detector for Super-Kamiokande.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.Through IceCUBE we access the very high end of the neutrino energy spectrum, preparing andsearching for new physics within, the astrophysical neutrino sample, and placing limits on Lorentzviolation from atmospheric neutrino data.Another goal of the group is the search for proton-decay, motivated by many unified theories,combining extensive phenomenological expertise with our experimental experience in Super-K andHyper-K. Further new physics will be addressed through the Atomic Interferometer ObservatoryNetwork (AION). Our contributions to the development of this series of UK-based quantum interferometerdetectors to explore ultra-light dark matter candidates and detect gravitational waves fromastrophysical sources, will involve detailed sensitivity studies to inform the design.

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，我们旨在解决中微子部门中的许多开放问题。 Wealso继续寻找新的物理学，解决包括质子衰变，超光的黑暗磨损和来自Astrophyiscal源的重力波，这是我们长期参与日本实验计划的参与：T2K，Super-Kamiokande和Hyper-Kamiokande和Hyper-Kamiokande均可在精确的中性振动中进行临时，我们的目的是氛围，目的是氛围中的氛围。违反麻血的侵犯的贡献，违反了我们的物质抗对称性的不对称性。为了促进成功的测量，我们正在追求对中微子相互作用横截面（尤其是电子中微子横截面），检测器响应和系统不确定性的详细理解。我们还通过开发需要分析大量数据量并维持超级卡米卡德的探测器所需的软件基础架构来支持这些努力。我们在加拿大的SNO+实验中也发挥了重要作用，在加拿大的主要datato搜索中，该搜索将搜索中性中微子的无β衰减，以便在该授予期间进行中性和质量，因此在此期间进行了批准。 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.Through IceCUBE we access the very high end of the neutrino energy spectrum, preparing andsearching for new physics within, the astrophysical neutrino sample, and placing limits on Lorentzviolation from大气中微子数据。该组的另一个目标是寻找质子 - 纪念日，这是由许多统一理论的动机，将广泛的现象学专业知识与我们在Super-K和Hyhyper-K中的实验经验相结合。将通过原子干涉仪观测网（AION）来解决进一步的新物理。我们对这一系列基于英国的量子干涉仪的开发的贡献，以探索超光线的候选暗物质候选物并检测来自腹腔物理来源的引力波，将涉及详细的灵敏度研究以告知设计。
