Experimental particle physics addresses some of the fundamentalquestions about the structure and behaviour of the Universe at thelevel of the smallest particles of matter, the quarks and the leptons,and the forces acting between them. We are exploring fundamentalproperties of particles at the the Large Hadron Collider (LHC) andalso exploring the nature of dark matter and neutrinos by developingand employing novel detection systems.We are contributing to the continued operation of the ATLAS project atthe Large Hadron Collider at CERN. We have constructed andcommissioned electronic systems and the software that drives them.From the beginning of data taking we have played a leading role insearches for exotic particles, the 2012 discovery of the Higgs boson,and studies of properties of the top quark. We are heavily invested in the upgrades to the ATLAS detector, which will allow for the collection of large datasets starting in 2021. Although there is ample indirect evidence for the existence of darkmatter as inferred from its gravitational interactions, it has not yetbeen directly detected in terrestrial laboratories. Direct detectionexperiments seek to observe dark matter scattering on target detectornuclei. We explore these issues through a world-leading dark mattersearch on DEAP-3600, a liquid Argon detector with unique potentialfor scaling to multi-tonne masses, with the DMTPC detector developmentprogramme to measure the dark matter wind, and the Lux-Zeplinexperiment. The group's expertise in high pressure TPCs is now beingutilised to carry out measurements relevant to the study of neutrinosas part of the Hyper-K experiment.Using detection techniques similar to those of our dark matter research, we are also involved in the the puzzle surrounding the matter anti-matter asymmetry in the Universe bystudying the elusive neutrino particle. We measure CP violation in the lepton sectorusing the T2K long baseline neutrino experiment in Japan.Our expertise in accelerator science will allow us to carry outstudies for the machine-detector interface for the High Luminosity LHCand ILC. We will also expand the interactions between ourphenomenology group and the experimental Neutrino and Dark Matter communities.

实验粒子物理学在最小的物质粒子、夸克和轻子的水平上，以及它们之间的作用力，解决了一些关于宇宙的结构和行为的基本问题。我们正在探索大型强子对撞机(LHC)粒子的基本性质，并通过开发和使用新的探测系统来探索暗物质和中微子的性质。我们正在为欧洲核子研究中心(CERN)大型强子对撞机的ATLAS计划的继续运行做出贡献。我们已经建造并委托了电子系统和驱动它们的软件。从数据获取的一开始，我们就在寻找奇异粒子、2012年发现希格斯玻色子和研究顶夸克的性质方面发挥了主导作用。我们在ATLAS探测器的升级方面投入了大量资金，这将使从2021年开始收集大型数据集成为可能。尽管有充分的间接证据证明暗物质的存在，这是从引力相互作用中推断出来的，但它还没有在地球实验室被直接探测到。直接探测实验试图观察到暗物质在目标探测器核上的散射。我们通过对DEAP-3600的世界领先的暗物质搜索来探索这些问题，DEAP-3600是一种具有独特的定标到数吨质量的液体Ar探测器，DMTPC探测器开发了测量暗物质风的程序，以及Lux-Zeplin实验。该小组在高压TPC方面的专业知识现在被用来进行与作为Hyper-K实验一部分的中微子的研究相关的测量。利用与我们暗物质研究类似的探测技术，我们还通过研究难以捉摸的中微子粒子，参与了宇宙中围绕物质反物质不对称性的谜题。我们使用日本的T2K长基线中微子实验测量了轻子区的CP破坏。我们在加速器科学方面的专业知识将使我们能够开展高亮度LHC和ILC的机器-探测器接口的研究。我们还将扩大我们的现象学小组与实验中微子和暗物质社区之间的互动。
