Programme of Research in Experimental Particle Physics at the University of Warwick: 2022-2025

拟议的研究范围涉及五个不同的领域：希格斯和新现象在ATLAS实验中的搜索；LHCb中含有美夸克的粒子的物理；中微子振荡和双β衰变实验的中微子物理；其他通向新物理的途径，例如Darkside，NuSTORM，FCC和量子传感器；探测器研发。它还包括外联和知识交流计划。更详细地说：o欧洲核子研究中心的ATLAS实验是在大型强子对撞机上运行的一个大型通用探测器，旨在搜索和研究希格斯玻色子以及新的奇异物质形式。我们的工作包括提高实验识别有趣事件的能力，以及帮助构建能够在升级的大型强子对撞机的新环境中工作的升级的探测器。我们还将通过帮助优化希格斯玻色子衰变到电子的重轻子对的事件的收集，对希格斯玻色子的详细研究做出贡献。我们还将寻找其他更重的奇异新玻色子。o我们的目标是在LHCb实验中进一步研究美丽介子衰变中的物质/反物质不对称性(CP破坏)。这一点很重要，因为我们在过去的实验中已经表明，在弱尺度上CP破坏的主要来源与CP破坏的标准模型机制是一致的。然而，宇宙学的考虑表明，自然界中应该有其他CP违例的来源，所以我们的目标是对美丽介子进行进一步的灵敏测试，以查看是否有任何其他CP违例来源的证据出现在这样的衰变中。我们还计划研究B介子的罕见衰变，这可能能够表明粒子物理标准模型之外存在新类型的相互作用。我们已经建造了T2K实验的一部分，目前正在日本运行。对T2K数据的分析有助于最终表明，中微子从一种类型转变为另一种类型。我们的目标是继续进行这项实验，以更好地测量这些振荡，并确定反中微子的振荡速度是否相同。同时，我们还在为下一代振荡实验做准备工作。这些项目，沙丘和Hyper-K，正在进入建设阶段，我们正在硬件和软件方面做出各种贡献，以帮助使实验能够为2026年左右的数据采集做好准备。我们还为超近地电磁和传奇实验做出了贡献，这些实验对中微子质量的大小很敏感，并将确定中微子是否是它自己的反粒子(即它是否是Majorana粒子)。o我们建议继续我们对许多其他项目的研究，这些项目有可能从不同的方向解锁新的物理，例如，为下一代中微子和缪子束的设计提供信息的加速器研究；暗物质搜索项目Darkside；下一代能量前沿对撞机(例如ILC和FCC)；量子传感器技术在粒子物理中的应用(例如，将量子传感器技术应用于中微子质量测量的QTNM计划)。O我们建议继续研究和发展位置和能量灵敏探测器，以应用于中微子实验和潜在的工业副产品应用。o我们会继续发展外展计划，包括为本地学校举办活动和在科普刊物上发表文章。o在大学强大的知识交流策略和精神的支持下，我们会继续寻求一切可能的知识交流途径。

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.
