This grant is to continue the group's programme of investigation into the properties of elementary particles and the fundamental forces of nature.One of the main objectives of this grant will be to support the exploitation of the LHC experiments which will be taking data during the period of this grant. The CMS experiment will continue to measure the Higgs particle, following its successful discovery in 2012. It will also be able to cover completely new areas of parameter space in searches for SUSY and other new phenomena such as finding evidence of potential dark matter candidates. The LHCb experiment will offer complementary tests of the Standard Model and beyond with the ability to look for extremely rare decays in flavour physics and to measure CP asymmetries in the decays of B mesons, both of which are sensitive to contributions from new physics. These experiments will make extensive use of Grid computing which the group will continue to develop and exploit, both for the LHC and for other experiments. The group will also be active in preparing the next generation of detectors for the high luminosity upgrade of the LHC.The T2K experiment will allow us to expand our understanding of the masses and mixings in the neutrino sector, and should provide key measurements which will guide us as to whether we ultimately could see evidence of CP violation in the neutrino sector. One of the other missing pieces of the neutrino puzzle is whether the neutrino is its own antiparticle. We are preparing the SuperNEMO experiment to attempt to determine if the neutrino is a Majorana particle and first data-taking will occur during the grant. Heavy neutrino-like particles are predicted in several new physics models and we are starting preparations for the SHiP experiment to search for these new particles.The group will be active in several experiments specifically searching for new physics. Direct conversion of muons to electrons is heavily suppressed in the Standard Model so any observation of this process would be a major discovery. The COMET experiment is searching for this process and will take data during the grant. Similarly, a measurable electric dipole moment for the electron could only arise through new physics and the eEDM experiment will continue to push down the limits for such an effect. Around a quarter of the universe is composed of dark matter and its nature is unknown. This has so far remained undetected in the laboratory and the group will continue its activity in searching for direct evidence of a dark matter candidate through the LUX and later LUX-ZEPLIN experiments.Accelerators to produce muon beams will be needed for future neutrino and muon collider experiments. The group is continuing its research in this area through the MICE experiment and nuSTORM studies. Proton beams also have potential applications for other scientific fields and for healthcare, and the group is studying how to apply these techniques in these areas. Understanding the LHC in terms of phenomenology is critical to comparing data to theory and the group is very active in this area.

该基金将用于继续该研究组的基本粒子性质和基本自然力的研究计划，其主要目标之一是支持大型强子对撞机实验的开发，该实验将在该基金期间获取数据。在2012年成功发现希格斯粒子之后，CMS实验将继续测量希格斯粒子。它还将能够覆盖参数空间的全新领域，以搜索超对称性和其他新现象，例如寻找潜在暗物质候选者的证据。LHC B实验将提供标准模型的补充测试，并能够在味道物理学中寻找极其罕见的衰变，并测量B介子衰变中的CP不对称性，这两者都对新物理学的贡献很敏感。这些实验将广泛使用网格计算，该小组将继续开发和利用网格计算，用于LHC和其他实验。T2 K实验将使我们能够扩大对中微子区质量和混合的理解，并提供关键的测量结果，指导我们最终是否能在中微子区看到CP破坏的证据。中微子之谜的另一个缺失部分是中微子是否是它自己的反粒子。我们正在准备SuperNEMO实验，试图确定中微子是否是马约拉纳粒子，第一次数据采集将在赠款期间进行。在几个新的物理模型中预测了重中微子类粒子，我们正在为SHiP实验做准备，以寻找这些新粒子。该小组将积极参与几个专门寻找新物理的实验。在标准模型中，μ子到电子的直接转换被严重抑制，因此对这个过程的任何观测都将是一个重大发现。彗星实验正在寻找这一过程，并将在赠款期间获取数据。类似地，电子的可测量电偶极矩只能通过新的物理学产生，而eEDM实验将继续降低这种效应的极限。宇宙的四分之一是由暗物质组成的，其性质尚不清楚。到目前为止，这一现象在实验室中还没有被发现，研究小组将继续通过LUX和后来的LUX-ZEPLIN实验寻找暗物质候选者的直接证据。未来的中微子和μ子对撞机实验将需要产生μ子束的加速器。该小组正在通过MICE实验和nuSTORM研究继续这一领域的研究。质子束在其他科学领域和医疗保健方面也有潜在的应用，该小组正在研究如何将这些技术应用于这些领域。从现象学的角度理解LHC对于将数据与理论进行比较至关重要，该小组在这一领域非常活跃。
