The Particle Physics Group at Manchester studies fundamental particles and their interactions, using data collected by experiments based at major international research centres. This research covers all aspects of experimental particle physics: the development of novel detector concepts; the design, construction and operation of large experiments; and the analysis of data. With this new grant, we will focus on using the data collected by these international experiments to search for new particles and new types of particle interactions. We will also carry out R&D for new detector concepts. We have four distinct strands of research:(1) Searching for new sources of CP-violation: CP-violation is the mechanism by which matter is more favourably produced than antimatter in fundamental particle interactions. It is well known that the level of CP violation in the Standard Model of Particle Physics is insufficient to explain the matter dominance that we observe in the Universe today. In this grant, we propose novel searches for CP violation using the ATLAS data. It is expected that a factor of ten improvement in sensitivity will be obtained for new sources of CP violation predicted by extensions to the Standard Model.(2) Dark matter: despite making up 85% of the mass of the Universe and playing a crucial role in its formation, the nature of this mysterious substance is still unknown. Using an ultra-sensitive Earth-based detector newly constructed to detect dark matter intersecting with the Earth as it travels through space, we develop new analysis strategies that enable us to identify and measure its properties, charting new regimes that were previously unexplorable.(3) Probing the interactions of the neutrino: Neutrinos are a window onto physics beyond our current understanding of the universe. The liquid-argon time-projection chamber of MicroBooNE has a spectacular ability to image the interactions of neutrinos and the particles produced in these interactions. Using these exquisite images, we will search for the evidence of new, never-before seen particles in these interactions, which would open up a new window onto how our Universe works.(4) Development of new detector technologies: Semiconductor sensors play a key role in many particle physics experiments, but are also central to many other imaging applications, from astronomy over medical applications to material research. Many future applications demand, in addition to micrometre-level spatial resolution, precise time information in the range of tens of picoseconds for particles registered in the sensors. We aim to provide a facility to characterise the timing properties of particle sensors that will be unique in the breadth of applicability due to its tuneable frequency. We will then apply this facility to particularly promising sensor technologies that are being explored by the particle physics community.

使用基于主要国际研究中心的实验收集的数据，曼彻斯特的粒子物理组研究基本颗粒及其相互作用。这项研究涵盖了实验粒子物理的各个方面：新型探测器概念的发展；大型实验的设计，构造和运行；以及数据分析。有了这项新的赠款，我们将重点介绍使用这些国际实验收集的数据来搜索新的粒子和新型的粒子相互作用。我们还将为新的检测器概念进行研发。我们有四个不同的研究范围：（1）寻找新的CP侵略来源：CP侵入是在基本粒子相互作用中比反物质更受欢迎的机制。众所周知，粒子物理标准模型中的CP违规水平不足以解释我们在宇宙中观察到的占主导地位。在这笔赠款中，我们建议使用Atlas数据进行新的搜索CP违规搜索。预计，对于标准模型扩展所预测的新的CP违规来源，将获得十倍的敏感性。（2）暗物质：尽管占宇宙质量的85％并在其形成中起着至关重要的作用，但这种神秘物质的性质仍然未知。使用新建造的超敏感地球检测器，以检测到地球穿过太空时与地球相交的暗物质，我们制定了新的分析策略，使我们能够识别和测量其特性，绘制了以前无法探索的新制度。（3）探索中性群体的相互作用：中源：中源是我们当前的现有理解的物理学的窗口。微酮的液体 - 阿贡液体投入室具有出色的能力，可以对中微子的相互作用和在这些相互作用中产生的颗粒进行成像。使用这些精美的图像，我们将搜索这些相互作用中新的，从未见过的粒子的证据，这将为我们的宇宙的运作方式打开一个新窗口。（4）新探测器技术的开发：半导体传感器在许多粒子物理实验中起关键作用，但也是许多其他成像应用的核心，从天文学过度进行医学应用到物质研究。除了微米级的空间分辨率外，许多未来的应用要求，在传感器中注册的粒子的数十个picseconds范围内，精确的时间信息。我们旨在提供一个设施，以表征粒子传感器的时序特性，这些粒子传感器的定时属性在适用性的广度上是唯一的。然后，我们将将此设施应用于粒子物理界正在探索的特别有前途的传感器技术。
