Bristol Particle Physics Consolidated Grant 2022-25

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。在欧洲核子研究中心大型强子对撞机的CMS实验中，我们将寻找新物理的信号，例如希格斯玻色子衰变中暗物质的产生。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。我们还将使用在大型强子对撞机上产生的非常大的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。我们将在CERN LHCb实验中使用补充方法来寻找新的物理。在这里，我们将在含有重夸克的介子的衰变中寻找新物理学的微妙特征，特别是在衰变到电子和µ子的过程中，目前的数据表明可能存在差异。我们将使用类似的方法来测试当前关于基本量子对称性的想法。我们将继续使用欧洲核子研究中心的NA62实验来研究介子的衰变，以寻找新的物理迹象，并继续使用BR2反应堆的固体实验来研究在5-10米的超短基线上的中微子振荡。我们还将参与Mu3e实验，以寻找轻子味道破坏，并为长基线中微子振荡实验DEU做准备。该小组将为未来的实验进行研发，包括CMS和LHCb的升级，以及欧洲核子研究中心SPS的飞船实验，该实验将使用非常高强度的光束来搜索作为标准模型以外物理特征的“暗粒子”。我们将继续为未来的希格斯工厂或强子对撞机详细设计和优化探测器。我们还将继续我们的计划，开发新的传感器和技术，包括与工业界合作，以便从我们在医疗保健、能源、安全和其他领域的工作中产生影响。

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 CMS experiment at the CERN LHC, we will search for signatures of new physics such as the production of dark matter in Higgs boson decays. 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. Here we will look for subtle signatures of new physics in the decays of mesons containing heavy quarks, particularly in decays to electrons and muons where current data indicates possible discrepancies. We will use similar approaches to test current ideas about the nature of fundamental quantum symmetries. We will continue to use the NA62 experiment at the CERN SPS to study the decays of kaons to look for signs of new physics, and the SOLID experiment at the BR2 reactor to study neutrino oscillations on an ultra-short baseline of 5-10m. We will also participate in the Mu3e experiment to search for lepton flavour violation, and prepare for the long-baseline neutrino oscillation experiment DUNE.The group will pursue R&D for future experiments, including upgrades for CMS and LHCb, and the SHiP experiment at the CERN SPS which will use a very high intensity beam to search for 'dark particles' that are signatures of physics beyond the Standard Model. We will continue to work on the detailed design and optimisation of detectors for a future Higgs factory or hadron collider.We will also continue our programme on the development of new sensors and technologies, including collaboration with industry in order to generate impact from our work in the healthcare, energy, security and other sectors.
