项目摘要

Our mission is to study fundamental particle interactions with matter, and from that learn about the subatomic nature of matter, and the broader implications of that research. This is the study of "Radiation for Science and Society", driven by the most important fundamental challenges in modern physics today.This grant proposal focuses on members of the Particle Physics Research Centre (PPRC) at Queen Mary University of London (QMUL) exploring the fundamental nature of the Universe. This will be achieved through studies of the Higgs boson, neutrinos and precision measurements of Standard Model processes, as well as searches for manifestations of new physics, namely deviations from the Standard Model. These goals are aligned with the STFC strategic priorities and to achieve these goals we also work on instrument construction for the ATLAS Upgrade and the DUNE experiments, as well as performing research and development toward future colliders and generic technology development targeting future accelerator based experiments and future neutrino and dark matter experiments. On ATLAS we will perform precision Higgs measurements, searches for rare Higgs boson processes that could elucidate our understanding of cosmological evolution of the Universe. We will search for new physics including Dark Matter via the Dark Machines collaboration and via rare decay searches, including di-Higgs production. We will study the Standard Model through a variety of high energy processes and through studies of rare B decays.On the ATLAS upgrade we will work on the construction of the Inner Tracker Upgrade and the Level 1 Calorimeter trigger to ensure that UK MoU contributions are met and that the maximum physics yield is achievable from that project. Likewise on the DUNE experiment we will work toward the construction of the near detector to ensure that the UK MoU requirements are met and that the physics output from the UK investment is maximised.Our contribution to the NOvA neutrino experiment focuses on the measurement of cross section data that are crucial to determination of oscillation parameters in the neutrino sector, and ultimately linked to the search for matter-antimatter asymmetries in neutrinos that could be the answer to why we live in a matter dominated Universe. This experimental activity will lead us naturally into exploitation of the DUNE experiment once construction of that is completed.To enable maximum physics output from the STFC programme as a part of the global particle physics programme, the PPRC works on the development of underpinning detector technology for future experiments. Mature technologies are spun out into near term goals, such as ATLAS Upgrade and DUNE activities. For the longer term we identify barriers such as the need for low mass tracking systems, technology that can function in high fluence, ergo high radiation, environments, data acquisition for current and next generation experiments. We also focus on evaluating emerging and novel technology with the intent to overcome challenges or limitations of the existing technologies, looking beyond the current generation of instruments. For example ways to reduce neutron background in future dark-matter and neutrino experiments, and possible applications to other STFC experimental programmes. We actively engage in impact through both societal and economic routes. QMUL was founded to facilitate education and opportunity for the local community. Today outreach and public engagement, particularly with the local community, remains strong. QMUL holds a gold watermark for public engagement. Outreach activities are embedded into the core ethos of our programme as a result of both our historic roots as an organisation, and the strategic vision shown by QMUL for public engagement. We also strive to work with the commercial sector and other stakeholders for economic benefit to the UK, and actively pursue technology innovation, IP generation

我们的使命是研究与物质的基本粒子相互作用，从中了解了物质的亚原子性质以及该研究的更广泛含义。这是对当今现代物理学最重要的基本挑战的驱动的“科学与社会辐射”的研究。该赠款提案重点关注伦敦皇后大学（QMUL）粒子物理研究中心（PPRC）的成员，探索了宇宙的基本本质。这将通过对希格斯玻色子，中微子和标准模型过程的精确度量以及寻找新物理学表现的搜索，即与标准模型的偏差的搜索来实现这一点。这些目标与STFC的战略重点保持一致，为了实现这些目标，我们还为Atlas升级和Dune实验的仪器构建工作，以及针对未来的Colliders和通用技术开发的研究和开发，以基于未来的加速器实验以及未来的中子和暗物质实验。在Atlas上，我们将执行精确的Higgs测量结果，寻找可以阐明我们对宇宙宇宙演化的理解的稀有希格斯玻色子过程。我们将通过深色机器协作以及包括Di-Higgs生产在内的罕见衰减搜索来搜索包括暗物质在内的新物理学。我们将通过各种高能量过程和稀有B衰变研究标准模型。在Atlas升级后，我们将致力于构建内部跟踪器升级和1级量热仪触发触发器，以确保满足英国谅解备忘录的贡献，并从该项目中实现最大的物理收益率。同样，在沙丘实验上，我们将努力建造近探测器，以确保满足英国谅解备忘录的要求，并最大程度地提高了英国投资的物理学的输出。您对NOVA NEDRINO实验的贡献侧重于测量横截面数据，这些数据对确定中性群体的确定以及最终链接到中性群体和最终链接的跨度数据至关重要，并且对于中性群体而言，以及最终的链接，以及对中性链接的链接。我们为什么生活在一个主导宇宙中的答案。一旦完成，这种实验活动将自然地导致我们从沙丘实验中剥削。为了使STFC计划的最大物理输出作为全球粒子物理计划的一部分，PPRC致力于开发未来实验的基础检测器技术。成熟的技术被跨成近期目标，例如Atlas升级和沙丘活动。从长远来看，我们确定了诸如低质量跟踪系统的需求，即可以在高流频率，ERGO高辐射，环境，数据采集的技术和下一代实验的数据中发挥作用的技术。我们还专注于评估新兴和新颖的技术，目的是克服现有技术的挑战或局限性，超越了当前的工具。例如，在未来的黑暗物体和中微子实验中减少中子背景的方法，以及其他STFC实验程序的应用。我们通过社会和经济路线积极参与影响。 QMUL的成立是为了促进当地社区的教育和机会。如今，宣传和公众参与，尤其是与当地社区的参与，仍然很强大。 Qmul拥有公众参与的金水印。由于我们作为组织的历史性根源以及QMUL在公众参与方面所展示的战略愿景，外展活动嵌入了我们计划的核心精神中。我们还努力与商业部门和其他利益相关者合作为英国的经济利益，并积极追求技术创新，IP生成
