Programme of Research in Experimental Particle Physics at the University of Warwick: 2015-2019.

拟议的研究范围包括五个不同的领域：ATLAS实验中的希格斯和新现象搜索; LHCb中包含美夸克的粒子物理学; T2 K和SuperNEMO中的中微子物理学;新的高强度质子，μ子和中微子束的加速器研究和开发;探测器研发。它还包括外联和知识交流方案。o欧洲核子研究中心的ATLAS实验，一个在大型强子对撞机上运行的大型通用探测器，旨在寻找和研究希格斯玻色子以及新的奇异形式的物质。我们的初步工作将是支持实验，促进其快速识别有趣事件的能力，以便记录和进一步分析。我们还将为2012年发现的希格斯玻色子的详细研究做出贡献。我们将通过优化衰变为τ轻子（电子的重亲戚）对的事件的耦合来实现这一目标。我们还将寻找其他更重的奇异新玻色子。我们的目标是进一步研究LHCb实验中Beautymesons衰变中的物质/反物质不对称性（CP破坏）。这是很重要的，因为我们在过去的实验中已经表明，在弱尺度下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来源的CP破坏，所以我们的目标是用美介子进行进一步的敏感测试，以了解是否有任何证据表明CP破坏的其他来源或其他新的物理学在自然界中可能出现在这样的衰变中。我们还计划研究B介子的罕见衰变，这可能表明在粒子物理学标准模型之外存在新型相互作用。这些都是非常轻的中性粒子，例如，由太阳发射，并在放射性β衰变中。他们最近被发现振荡，即。从一种类型转变为另一种类型，同时它们也在传播。我们已经建立了T2 K实验的一部分，该实验目前正在日本运行。最近对其数据的分析发现了μ介子到电子型中微子的新型振荡。我们的目标是继续进行这项实验，更好地测量这种新发现的效应，并用反中微子寻找它。我们还计划为SuperNEMO实验做出贡献，该实验旨在确定中微子的性质，即所谓的狄拉克粒子或马约拉纳粒子。前者有不同的反粒子，而后者是它自己的反粒子。这个问题可以通过寻找没有中微子伴随的双β衰变来解决。o我们提议继续研究和开发用于产生质子、μ子和中微子束的高功率加速器。我们设想的是未来的中微子工厂，尽管其他机器也可以从我们的研究中受益。这样的中微子工厂，如果建成，将继续发展研究主题的中微子振荡和物质反物质不对称的中微子如上所述。o我们建议继续研究和开发位置和能量敏感探测器，用于中微子实验和潜在的自旋探测器。o我们会继续发展外展计划，包括为本地学校举办活动，以及在科普刊物上发表文章。o我们会以大学的策略和知识风气为后盾，交流，我们将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 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 initial work will be to support the experiment by contributing to its ability to identify interesting events rapidly for recording and further analysis. We will also contribute to the detailed study of the Higgs boson which was discovered in 2012. We will do this by helping to optimise the coeection 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 or other new physics in Nature may 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. These are very light, neutral particles which are emitted, for example, by the sun, and in radioactive beta decay. They have recently been found to oscillate, ie. transmute from one type to another, while they propagate. We have built part of the T2K experiment which is now operating in Japan. Analyses of its data recently found new types of oscillations of muon to electron type neutrinos. We aim to continue running this experiment, to better measure this newly-discovered effect, and also to search for it with anti-neutrinos. We further plan to contribute to the SuperNEMO experiment, which aims to determine the nature of the neutrino as 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.
