项目摘要

The Particle Physics Group at Manchester studies fundamental particles and their interactions, with experiments based at major international research centres. This research is performed in international collaborations and 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.The Group plays a leading role on two of the main experiments at tbe Large Hadron Collider (LHC), which produces proton-proton collisions at the highest energies currently accessible in accelerators. On the ATLAS and LHCb experiments, we test the Standard Model (SM) of Particle Physics with unprecedented precision and search for new physics beyond the SM. These studies include novel measurements of the properties of the strong and electroweak interactions. We also study the properties of the Higgs boson and its relationship to the heaviest particle, the top-quark.The LHCb experiment is designed to study the properties of particles that are built from the heavy bottom and charm quarks. Detailed studies of their production and decays provide a window to new physics and allow us to study fundamental questions such as the origin of the matter-antimatter asymmetry. We are also active on preparing future upgrades to both the ATLAS and LHCb experiments, which will allow their discovery reach to be significantly extended.The Muon g-2 experiment in the US will examine the precession of muons that are subjected to a magnetic field. The main goal is to test predictions of this value by measuring the precession rate to a precision of 0.14 parts per million. If there is an inconsistency, it could indicate the Standard Model is incomplete. The goal of the Mu2e experiment is to find conversions of muons into electrons without the emission of neutrinos. Understanding the properties of the elusive neutrino is another priority of our research programme. With the SuperNEMO detector, located in the Modane Underground Laboratory, we search for neutrinoless double beta decay, a process that has never been observed before. Its observation would indicate that neutrinos are their own antiparticles and it will provide a measurement of the neutrino mass. A different kind of experiment, DUNE, will use a novel technology based on liquid argon to detect neutrinos that have been sent through the Earth, in a beam pointing from Fermilab in Chicago to a mine in South Dakota. The goal of this experiment is to learn whether neutrinos violate the fundamental symmetry between matter and antimatter. The experiment could also detect neutrinos from a supernova explosion. A similar kind of experiment (SBND/MicroBooNE) uses neutrinos close to the source at Fermilab to search for 'sterile' neutrinos that do not interact via any of the fundamental interactions of the Standard Model except gravity.The DarkSide experiment will search for dark matter from space via its interactions with liquid argon nuclei and subsequent light emission and detection using highly sensitive silicon photosensors.Modern Particle Physics experiments contain sophisticated technology to detect particles. The Manchester Group leads an extensive reasearch programme on developing novel detection devices, such as diamond detectors. These novel technologies have many potential applications beyond Particle Physics research, in areas such as medical physics and security applications. Particle Physics experimentation requires the reconstruction and analysis of large, complex data sets. We operate a large computing facility which supports data analysis for several of these large projects. We develop and apply sophisticated analysis techniques to large data sets.Finally, through our outreach programme, we communicate the results of our research to the public through the media, public lectures and masterclasses.

曼彻斯特的粒子物理组研究基本颗粒及其相互作用，其实验基于主要的国际研究中心。这项研究是在国际合作中进行的，涵盖了实验粒子物理学的各个方面：新型探测器概念的发展；大型实验的设计，构造和运行；数据分析。该小组在大型强子对撞机（LHC）的两个主要实验中起主要作用，该实验在当前在加速器中可访问的最高能量时产生质子 - 蛋白碰撞。在ATLA和LHCB实验中，我们以前所未有的精度测试粒子物理学的标准模型（SM），并在SM以外搜索新物理学。这些研究包括对强和电动相互作用的性质的新测量。我们还研究了希格斯玻色子的特性及其与最重的粒子的关系，即Quark。LHCB实验旨在研究从较重的底部和魅力夸克（Charm Quarks）构建的颗粒的性质。对其生产和衰减的详细研究为新物理学提供了一个窗口，并使我们能够研究基本问题，例如物质 - 抗逆念剂不对称的起源。我们还积极准备对ATLA和LHCB实验的未来升级，这将使他们的发现范围可显着扩展。美国的MUON G-2实验将检查经受磁场的MUON的进步。主要目标是通过测量进进率的精度为0.14分，测试该值的预测。如果存在不一致，则可能表明标准模型不完整。 MU2E实验的目的是在没有中微子发射的情况下找到兆次转化为电子。了解难以捉摸的中微子的特性是我们研究计划的另一个优先事项。借助位于摩登烷地下实验室的超级核检测器，我们搜索中微子双β衰变，这是以前从未观察到的过程。它的观察结果表明，中微子是他们自己的反植物，它将提供中微子质量的测量。 Dune的另一种实验将使用基于液体氩气的新技术来检测已通过地球发送的中微子，该中微子是从芝加哥的费米拉布（Fermilab）到南达科他州（South Dakota）的一个矿山的光束。该实验的目的是了解中微子是否违反了物质和反物质之间的基本对称性。该实验还可以从超新星爆炸中检测中微子。类似类型的实验（SBND/Microboone）使用靠近Fermilab的源的中微子来搜索“无菌”中微子，这些中微子不会通过标准模型的任何基本相互作用而不会相互作用，除了重力外，Darkside实验将通过其与液体型核心的相互作用的相互作用来寻找暗物质，并使用高度的粒子和后续式sillections siltersicts搜索暗物质，从而搜索深色物质。检测颗粒的精致技术。曼彻斯特集团（Manchester Group）领导着一项广泛的探究计划，以开发新的检测设备，例如钻石探测器。这些新型技术在粒子物理研究之外，在医学物理和安全应用等领域中具有许多潜在的应用。粒子物理实验需要重建和分析大型复杂数据集。我们经营着一个大型计算设施，该设施支持其中几个大型项目的数据分析。我们将复杂的分析技术开发到大型数据集中。在本文中，通过我们的外展计划，我们通过媒体，公共讲座和大师班将研究结果传达给公众。
