项目摘要

The scope of the proposed research lies in five distinct areas: Higgs and new phenomena searches at the ATLAS Experiment; the physics of particles containing the beauty quark at LHCb; the physics of neutrinos with neutrino oscillation and double-beta decay experiments; other routes to new physics with e.g. Darkside, NuSTORM, FCC and quantum sensors; detector R&D. It also includes Outreach and Knowledge Exchange programmes. In more detail:o The ATLAS experiment at CERN, a large, general purpose detector operating at the LHC was designed to search for and study the Higgs boson, as well as new exotic forms of matter. Our work involves contributing to the experiment's ability to identify interesting events as well as helping to construct an upgraded detector able to work in the new environment of an upgraded LHC. We will also contribute to the detailed study of the Higgs boson by helping to optimise the collection of events in which it decays to pairs of tau leptons, heavy relatives of the electron. We will also look for other, heavier exotic new bosons.o We aim to further our research into matter/anti-matter asymmetry (CP Violation) in the decays of Beauty mesons at the LHCb experiment. This is important, because we have shown in past experiments that the leading source of CP violation at the weak scale is consistent with the Standard Model mechanism of CP violation. However, cosmological considerations indicate that there should be other sources of CP violation in Nature, so we aim to make further sensitive tests with beauty mesons, in order to see if any evidence for additional sources of CP violation appear in such decays. We also plan to study rare decays of B mesons, which may be able to indicate the presence of new types of interactions outside the Standard Model of particle physics.o The elucidation of the properties of neutrinos. We have built part of the T2K experiment which is now operating in Japan. Analyses of T2K data has helped to show conclusively that neutrinos transmute or `oscillate' from one type to the other. We aim to continue running this experiment, to better measure these oscillations, and to establish whether the rate of oscillation is the same for anti-neutrinos. In parallel, we are deeply involved with preparations for the next generation of oscillation experiment. These projects, DUNE and Hyper-K, are entering the construction phase and we are making various contributions in both hardware and software to help enable the experiments to be ready for data taking around 2026. We are also contributing to the SuperNEMO and LEGEND experiments, which are sensitive to the scale of the neutrino mass and will determine whether the neutrino is it's own anti-particle (i.e. whether it is a Majorana particle or not).o We propose to continue our research across a raft of other projects with the potential to unlock new physics from different directions i.e. accelerator studies which are informing the design of next generation neutrino and muon beams; the dark matter search project Darkside; next generation energy frontier colliders (e.g. ILC and FCC); the application of quantum sensor technology to particle physics (e.g. the QTNM project applying quantum sensor technology to the measurement of neutrino mass). o We propose to continue our research and development of position- and energy-sensitive detectors for applications in neutrino experiments and with potential spin-off applications in industry.o We will continue to develop our outreach programme which includes activities for local schools and articles in popular science publications.o Supported by a strong University strategy and ethos in knowledge exchange, we will continue to pursue all avenues for possible knowledge exchange.

拟议研究的范围在于五个不同的领域：在Atlas实验中进行的希格斯和新现象搜索； LHCB上包含美容夸克的颗粒物理学；中微子振荡和双β衰减实验的中微子物理学；使用例如新物理学的其他路线暗边，nustorm，FCC和量子传感器；检测器研发。它还包括外展和知识交流计划。更详细地：o在CERN的ATLAS实验，在LHC上运行的大型通用检测器旨在搜索和研究Higgs玻色子以及新的外来物质形式。我们的工作涉及为实验确定有趣事件的能力做出贡献，并帮助构建升级的检测器能够在升级的LHC的新环境中工作。我们还将通过帮助优化其腐烂到tau瘦素的事件的收集来为希格斯玻色子的详细研究做出贡献。我们还将寻找其他较重的异国情调的新玻色子。这很重要，因为我们在过去的实验中表明，在弱规模上违反CP的主要来源与CP违规的标准模型机制一致。但是，宇宙学的考虑表明，本质上应该还有其他违反CP的来源，因此我们旨在对美容媒介进行进一步的敏感测试，以查看是否有任何证据表明在这种衰减中出现了其他违规来源。我们还计划研究B介子的罕见衰变，这可能能够表明在粒子物理学的标准模型之外存在新型的相互作用。我们已经建立了现在在日本运行的T2K实验的一部分。对T2K数据的分析有助于最终证明中微子从一种类型转换到另一种类型。我们的目标是继续运行该实验，以更好地测量这些振荡，并确定抗中性替氏菌的振荡速率是否相同。同时，我们与下一代振荡实验的准备非常重要。这些项目，沙丘和超级K，正在进入施工阶段，我们正在为硬件和软件做出各种贡献，以帮助使实验能够准备好2026年左右的数据。我们也为超级诺和传说实验做出了贡献，这些实验对中性群体的规模敏感，并将确定中性群是eTimantion int to int themantiation iT ransemant at i at i at i at Anti part we It IT IT IT IT IT IT IT IT IT）。我们在其他一系列项目中进行的研究可能会从不同方向上解开新物理学的研究，即加速器研究，这些研究为下一代中微子和MUON束的设计提供了信息；暗物质搜索项目暗边；下一代能量前沿山脉（例如ILC和FCC）；将量子传感器技术应用于粒子物理学（例如，将量子传感器技术应用于中微子质量的QTNM项目）。 o我们建议继续我们对中微子实验中应用的位置和能量敏感探测器的研究和开发。
