Programme of Research in Experimental Particle Physics at the University of Warwick: 2012-2016.

拟议的研究范围涉及五个不同的领域：LHCb中包含美夸克的粒子物理；T2K和SuperNEMO的中微子物理；ATLAS的希格斯和新现象搜索；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。更详细地说：o我们的目标是在LHCb实验中进一步研究美色子衰变中的物质/反物质不对称(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的CP破坏源，所以我们的目标是用美介子进行进一步的灵敏测试，以看看是否有任何证据表明在这种衰变中可能会出现CP破坏的其他来源或其他新物理。这些是非常轻的中性粒子，例如由太阳发射，在放射性贝塔衰变中。最近发现它们是振荡的，即。在它们繁殖的同时，从一种类型转化为另一种类型。我们已经建造了T2K实验的一部分，目前正在日本运行。对早期数据的分析给出了诱人的线索，表明了以前从未观察到的从µ子到电子型中微子的振荡。我们的目标是继续进行这项实验，希望能证实这些初步的暗示。如果得到证实，这种巨大的效应将提供继续寻找中微子和反中微子振荡之间的不对称性的机会。我们进一步计划为超负电子物理实验做出贡献，该实验旨在确定中微子的性质，即所谓的狄拉克或马约拉纳粒子。前者具有明显的反粒子，而后者是其自身的反粒子。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我们最近加入了欧洲核子研究中心的ATLAS实验，这是大型强子对撞机的一个通用探测器。我们最初的工作将是支持该实验，使其能够快速识别感兴趣的事件，以便记录和进一步分析。我们还将为寻找希格斯玻色子做出贡献，希格斯玻色子是粒子物理标准模型中最后缺失的部分。我们将通过帮助优化其衰变到电子的重轻子对的搜索来做到这一点。o我们建议继续研究和开发用于产生质子、介子和中微子的高功率加速器。我们考虑的是未来的中微子工厂，尽管其他机器可能会从我们的研究中受益。如果建成这样的中微子工厂，将继续发展上文概述的中微子振荡和中微子物质-反物质不对称的研究主题。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在大学强大的策略和KE的精神支持下，我们会继续寻求各种可能的知识交流途径。

The scope of the proposed research lies in five distinct areas: the physics of particles containingthe beauty quark at LHCb; the physics of neutrinos with T2K and SuperNEMO; Higgs and new phenomena searches at ATLAS; 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 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.o The elucidation of the properties of neutrinos. These are very light, neutral particles which areemitted, for example, by the sun, and in radioactive beta decay. They have recently been found tooscillate, ie. transmute from one type to another, while they propagate. We have built partof the T2K experiment which is now operating in Japan. Analyses of early data give tantalising hints of the previously unobserved oscillations of muon to electron type neutrinos. We aim to continue running this experiment, hopefully to confirm these preliminary hints. If confirmed, the largeness of the effect will offer the chance to go on to look for asymmetries between the oscillations of neutrinos and 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 have recently joined the ATLAS experiment at CERN, a general purpose detector operating at the LHC. 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 search for the Higgs boson, the last missing piece in the Standard Model of particle physics. We will do this by helping to optimise the search for its decays to pairs of tau leptons, heavy relatives of the electron.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 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 KE, we will continue to pursue all avenuesfor possible knowledge exchange.
