Bristol Particle Physics Consolidated Grant 2015-19

布里斯托尔粒子物理学小组将寻找超越标准模型的物理证据，并致力于了解新现象的性质。我们将使用一系列的方法和实验来进行这项研究。在大型强子对撞机上的CERN CMS实验中，我们将使用具有“缺失能量”的事件来寻找暗物质和超对称粒子产生的信号。在没有发现的情况下，我们将把我们观察到的统计信息与宇宙学和直接暗物质搜索的结果结合起来，以排除潜在的新物理理论。我们还将使用大型强子对撞机产生的超大数据集来研究顶夸克的产生和性质，顶夸克是一种具有独特性质的标准模型粒子。我们将使用补充方法在CERN LHCb实验中搜索新物理，寻找在包含重夸克的介子衰变中显现出来的新物理的微妙特征。我们将使用类似的方法来测试目前关于基本量子对称性的想法。一些新的实验正在准备中，将在授权期内或之后不久准备好使用。欧洲核子研究中心的NA62实验将研究介子的衰变，以寻找新的物理迹象。BR2反应堆的固体实验将在5-10米的超短基线上研究中微子振荡。欧洲核子研究中心SPS的飞船实验将使用非常高强度的光束来搜索作为超越标准模型的物理特征的“暗粒子”。最后，我们已经开始为未来的直线对撞机探测器的详细设计和优化做准备。我们将继续我们的粒子探测器研发计划，为CMS和LHCb的升级做出贡献，为设计和建造新的实验，以及开发新的传感器和技术做出贡献。这一方案的一个重要部分将是与工业界和其他学术学科合作，以便从我们的工作中产生影响。

The Bristol particle physics group will search for evidence of physics beyond the Standard Model, and work to understand the properties of new phenomena. We will carry out this study using a range of approaches and experiments.At the CERN CMS experiment at the LHC, we will search for signatures of the production of dark matter and supersymmetric particles, using events with 'missing energy'. In the absence of a discovery, we will combine statistical information from our observations with results from cosmology and direct dark matter searches, to rule out potential theories of new physics. We will also use the very large datasets produced at the LHC to study the production and properties of the top quark, a standard model particle with unique properties.We will use a complementary approach to search for new physics at the CERN LHCb experiment, looking for subtle signatures of new physics that manifest themselves in the decays of mesons containing heavy quarks. We will use similar approaches to test current ideas about the nature of fundamental quantum symmetries.A number of new experiments are being prepared, and will be ready for use within or shortly after the grant period. The NA62 experiment at the CERN SPS will study the decays of kaons to look for signs of new physics. The SOLID experiment at the BR2 reactor will study neutrino oscillations on an ultra-short baseline of 5-10m. The SHiP experiment at the CERN SPS will use a very high intensity beam to search for 'dark particles' that are signatures of physics beyond the Standard Model. Finally, we have begun to make preparations for the detailed design and optimisation of detectors for a future linear collider.We will continue our programme of particle detector R&D, contributing to the upgrade of CMS and LHCb, to the design and construction of new experiments, and to the development of new sensors and technologies. An important part of this programme will be collaboration with industry and other academic disciplines, in order to generate impact from our work.
