The scope of the proposed research lies in four distinct areas: the physics of particles containing the beauty quark, and the physics of neutrinos, accelerator and detector research and development. It also includes Outreach and Knowledge Exchange programmes, as follows: o We aim to further our research into matter/anti-matter asymmetry (CP Violation) with Beauty mesons at the LHCb experiment. This is important, because we have shown in past experiments that the leading source of CP violation at low energies 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 in Nature may appear there. 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 propose to build part of the T2K experiment, operate it and analyse its data., This experiment aims to determine the details of the oscillation behaviour. In particular, it aims to establish the rate and extent of oscillations between muon- and electron-neutrinos, and to derive related information on neutrino masses. o We propose to continue our research and development on the Neutrino Factory project, which aims to provide crucial information for the design of such a particle accelerator, which, in turn, could be built in the future to search for CP violation in the oscillations of neutrinos. 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 KE, we will continue to pursue all avenues for possible KE.

拟议研究的范围在于四个不同的领域：包含美容夸克的颗粒物理学，以及中微子，加速器和探测器的研究和开发的物理学。它还包括外展和知识交流计划，如下所示：o我们旨在通过LHCB实验中的美容媒介进一步研究物质/反物质不对称（CP违规）。这很重要，因为我们在过去的实验中表明，低能量下违反CP的主要来源与CP违规的标准模型机制一致。但是，宇宙学的考虑表明，本质上应该还有其他违反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，以查看是否可能出现任何自然界中其他CP违规来源的证据。 o阐明中微子的性质。这些是非常轻的，中性的颗粒，例如由太阳和放射性β衰减发出。最近发现它们是振荡的，即。在传播时，将一种类型传输到另一种类型。我们建议建立一部分T2K实验，对其进行操作并分析其数据。该实验旨在确定振荡行为的细节。特别是，它旨在建立穆恩和电子中性菌之间振荡的速率和程度，并得出有关中微子质量的相关信息。 o我们建议继续我们的中微子工厂项目的研发，该项目旨在为这种粒子加速器的设计提供关键信息，而这种粒子加速器的设计又可以在将来建造以在中微子的振荡中搜索CP违规。 o我们建议继续我们对中微子实验中应用以及潜在的衍生产品应用的位置和能量敏感探测器的研究和开发。 o我们将继续制定我们的外展计划，其中包括当地学校的活动和流行科学出版物的文章。 o在KE的强大大学战略和精神的支持下，我们将继续追求所有可能的KE途径。
