Capital Equipment: Computing Cluster Upgrade and Neutrino Detector Laboratory Upgrade

拟议的研究范围包括五个不同的领域：ATLAS的希格斯研究和新现象搜索; LHCb的含有美夸克的粒子物理学; T2 K，SuperNEMO和LBNE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实验是一个在大型强子对撞机上运行的通用探测器。我们在实验中的参与越来越多，最近任命了一位新教授在该地区，以及两个新的博士后研究员。我们建议的努力将是支持实验，促进其能力，以确定有趣的事件迅速记录和进一步分析。我们还将继续对最近发现的希格斯玻色子的性质进行详细研究，希格斯玻色子被认为是与所有物质耦合的粒子，并赋予其质量。我们将通过帮助优化其衰变到τ轻子对的搜索来做到这一点，τ轻子是电子的重亲戚。我们的目标是在LHCb实验中进一步研究Beauty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CP破坏的来源，所以我们的目标是用美介子进行进一步的敏感测试，以观察是否有任何证据表明CP破坏的其他来源或其他自然界中的新物理可能出现在这样的衰变中。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。这些神秘的粒子被称为振荡，即。从一种类型转变为另一种类型，同时它们也在传播。我们建立了T2 K实验的一部分，在日本研究这些现象。对实验数据的分析给出了以前未观察到的μ介子到电子型中微子振荡的早期暗示，最近的观测证实了这一点。我们的目标是继续进行这个实验，更详细地研究这些影响。这种效应的巨大性为我们提供了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，将继续发展上述中微子振荡和中微子的物质-反物质不对称性的研究主题。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，并可能在工业上产生附带应用。o我们会继续发展外展计划，包括为本地学校举办活动，以及在科普刊物上发表文章。o在坚尼地大学的策略和校风支持下，我们会继续寻求各种途径，进行知识交流。

The scope of the proposed research lies in five distinct areas: Higgs studies and new phenomena searches at ATLAS; the physics of particles containing the beauty quark at LHCb; the physics of neutrinos with T2K, SuperNEMO and LBNE; 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 is a general purpose detector operating at the LHC. Our participation in the experiment is growing with the recent appointment of a new professor in the area, as well as two new postdoctoral fellows. Our proposed effort will be to support the experiment by contributing to its ability to identify interesting events rapidly for recording and further analysis. We will also continue our detailed studies of the properties of the recently discovered Higgs boson, thought to be the particle which couples to all matter, giving it mass. 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 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 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 are emitted, for example, by the sun, and in radioactive beta decay. These mysterious particles are known to oscillate, ie. transmute from one type to another, while they propagate. We built part of the T2K experiment which studies these phenomena in Japan. Analyses of data taken at the experiment gave early hints of the previously unobserved oscillations of muon to electron type neutrinos, and more recent observations have confirmed this. We aim to continue running this experiment, to study these effects in greater detail. The largeness of the effect offers 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 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 detectors for applications in neutrino experiments and with potential spin-off applications in industry. A particular focus of this effort is the LBNE neutrino oscillation experiment.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 KE, we will continue to pursue all avenues for possible knowledge exchange.
