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 T2K and SuperNEMO; accelerator research and development for new high intensity proton, muon and neutrino beams; 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 Beautymesons at the LHCb experiment. This is important, because we have shown in past experiments thatthe leading source of CP violation at the weak scale is consistent with the Standard Model mechanismof CP violation. However, cosmological considerations indicate that there should be other sourcesof CP violation in Nature, so we aim to make further sensitive tests with beauty mesons, in orderto see if any evidence for additional sources of CP violation appear in such decays. We also plan to studyrare 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 coming to the end of the preparatory 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 further plan to contribute to the SuperNEMO experiment, which aims to determine the nature of the neutrino as a so-called Dirac or Majorana particle. The former has distinct anti-particles, while the latter is its own antiparticle. This question may be resolved by searching for double beta decay accompanied by no neutrinos. We will contribute to the analysis of data obtained by a "demonstrator module" attempting to observe such decays.o We propose to continue our research and development of high power accelerators for the generation of proton, muon and neutrino beams. We have in mind future neutrino factories, although other machines could benefit from our research. Such neutrino factories, if built, would continue to develop the theme of research into neutrino oscillations and matter-antimatter asymmetry of neutrinos as outlined above. Such machines could also bring many benefits to medicine and industry.o We propose to continue our research and development of position- and energy-sensitive detectorsfor 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 schoolsand articles in popular science publications.o Supported by a strong University strategy and ethos in knowledge exchange, we will continue to pursue all avenuesfor 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；具有T2K和Supernemo的中微子物理学；新的高强度质子，MUON和中微子束的加速器研究和开发；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违规的标准模型机构一致。但是，宇宙学的考虑表明，自然界中应有其他违反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落中出现了其他CP违规来源的证据。我们还计划研究B介子的腐烂，这可能能够表明粒子物理标准模型之外存在新型相互作用。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Hyper-K）即将到达准备阶段，我们正在在硬件和软件中做出各种贡献，以帮助使实验准备好2026年左右的数据。我们进一步计划为超级运动实验做出贡献，该实验旨在确定中性群体作为所谓的Dirac或Majorana或Majorana粒子的性质。前者具有独特的抗颗粒，而后者是其自身的反粒子。可以通过搜索双重β衰变（不含中微子）来解决这个问题。我们将为试图观察这种衰减的“演示器模块”获得的数据进行分析。我们有未来的中微子工厂，尽管其他机器可以从我们的研究中受益。如上所述，这种中微子工厂将继续发展为中微子振荡和中微子不对称的研究主题。这样的机器也可能为医学和行业带来许多好处。
