It is an exceptional time for discoveries in particle physics and particle astrophysics and the research we wish to conduct in this STFC consolidated grant programme at Sheffield is at the heart of this action. Foremost recently has been the discovery by ATLAS of a Higgs boson particle. Members of the group led and helped to develop the key 4-lepton analysis upon which the discovery was based. We will now use our expertise to measure carefully the properties of the new particle to establish whether it is the Higgs boson predicted by theory, or something else. We will also search for squark and gluino particles predicted by supersymmetry theory, which will be the main target of the next, higher energy, run of the LHC. Preparing for the future, we will expand our role in the ATLAS upgrade programme to build key components of a new ATLAS tracker. Our involvement in the T2K experiment in Japan also greatly benefited from confirmation of a non-zero third neutrino mixing angle, a result fundamental to our understanding of the neutrino. The group's respected work in neutrino analyses for T2K, particularly of so-called charge current and neutral current events, will continue along with international responsibilities for data management and for the critical light injection calibration system. However, bolstered by the exciting new results we will now also accelerate participation in next generation long baseline neutrino experiment for CP violation aimed to unravel the mystery of antimatter in the Universe, notably using LBNE/F in the US and Hyper-K in Japan. For these our particular focus will be on detector construction. For the precursor LAr1-ND experiment at Fermilab we plan to construct the central Anode Plane Array for the detector, while working also on our pioneering liquid argon R&D. We will also establish novel detector prototypes at the new CERN-based neutrino platform and for LBNE/F itself. Closely related here will be work on the MICE experiment towards a potential future neutrino factory, plus related R&D on high power particle beam targets for future neutrino beams and experiments. For particle astrophysics we plan to expand work on gravitation waves, through specialist noise analysis for Advanced Ligo, and develop new effort on dark matter, thought to comprise 90% of the Universe. There is strong motivation here because the US LUX experiment recently produced a step-change in sensitivity to dark matter particles. We will complete leading analysis for the EDELWEISS experiment and then lead key simulations for the upcoming LZ experiment in the US. Following our pioneering work on detectors with sensitivity to galactic signatures, the group will also lead analysis and construction tasks for the DRIFT direction sensitive experiment at Boulby and the new DM-ICE250 NaI experiment, which US collaborators recently agreed will be hosted at Boubly. DM-ICE will seek a new annual modulation signal for dark matter. These experiments are all searching WIMP particles, but we will also expand study of axions as a potential alternative. Meanwhile, our generic detector R&D and knowledge exchange programme is vital to underpinning the group's expertise and skills-base. It benefits from our historic links to the Boulby deep underground science laboratory but critically now involves multiple industrial and non-STFC projects. Noteworthy aims now will be to complete our DECC-funded programme on muon tomography for climate change, develop new instrumentation for radon assay, spin-out work on novel motor control electronics via a new patent and continue development of novel welding technology. It is interesting that our long-standing efforts to develop liquid argon technology for neutrino physics are also relevant to medical imaging requirements. We plan to complete a new prototype instrument, building on a recent MRC award. This all reflects the group's commitment to contributing to societal and impact agendas.

这是粒子物理学和粒子天体物理学发现的特殊时刻，我们希望在谢菲尔德的STFC综合资助计划中进行的研究是这一行动的核心。最近最重要的是ATLAS发现了希格斯玻色子粒子。该小组的成员领导并帮助开发了该发现所基于的关键4轻子分析。我们现在将利用我们的专业知识仔细测量新粒子的性质，以确定它是否是理论预测的希格斯玻色子，或者其他东西。我们还将寻找超对称理论预测的夸克和胶子粒子，这将是下一个更高能量的LHC运行的主要目标。为未来做好准备，我们将扩大我们在ATLAS升级计划中的作用，以构建新ATLAS跟踪器的关键组件。我们参与日本的T2 K实验也大大受益于非零的第三中微子混合角的确认，这是我们理解中微子的基础。该小组在T2 K中微子分析方面的受人尊敬的工作，特别是所谓的充电电流和中性电流事件，将继续沿着国际数据管理和临界光注入校准系统的责任。然而，在令人兴奋的新结果的支持下，我们现在也将加速参与下一代长基线中微子实验，以解开宇宙中反物质的奥秘，特别是使用美国的LBNE/F和日本的Hyper-K。对于这些，我们将特别关注探测器的构造。对于费米实验室的前体LAr 1-ND实验，我们计划为探测器建造中央阳极平面阵列，同时也致力于我们开创性的液态氩研发。我们还将在新的基于CERN的中微子平台和LBNE/F本身建立新的探测器原型。与此密切相关的将是MICE实验的工作，以实现未来潜在的中微子工厂，以及未来中微子束和实验的高功率粒子束目标的相关研发。 对于粒子天体物理学，我们计划通过高级Ligo的专业噪声分析来扩大引力波的工作，并在暗物质方面开展新的工作，暗物质被认为占宇宙的90%。这里有强烈的动机，因为美国LUX实验最近产生了对暗物质粒子敏感性的阶跃变化。我们将完成EDELWEISS实验的主要分析，然后领导即将在美国进行的LZ实验的关键模拟。继我们对银河系特征敏感的探测器的开创性工作之后，该小组还将领导在Boulby进行的DRIFT方向敏感实验和新的DM-ICE 250 NaI实验的分析和建设任务，美国合作者最近同意将在Boubly进行。DM-ICE将为暗物质寻找新的年度调制信号。这些实验都是在寻找WIMP粒子，但我们也将扩大对轴子的研究，作为一种潜在的替代方案。 与此同时，我们的通用检测器研发和知识交流计划对于巩固集团的专业知识和技能基础至关重要。它受益于我们与博尔比地下科学实验室的历史联系，但现在涉及多个工业和非STFC项目。现在值得注意的目标将是完成我们的DECC资助的气候变化μ子断层扫描计划，开发新的氡分析仪器，通过新的专利开展新型电机控制电子产品的工作，并继续开发新型焊接技术。有趣的是，我们长期以来为中微子物理学开发液氩技术的努力也与医学成像要求有关。我们计划完成一个新的原型仪器，在最近的MRC奖的基础上。这一切都反映了该集团致力于为社会和影响议程做出贡献。
