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.

实验粒子物理学解决了有关物质，夸克和叶子的最小粒子的宇宙结构和行为的一些基本问题，以及它们之间作用的力。我们正在大型强子对撞机（LHC）Ando探索颗粒的基本形象，并通过开发和采用新型检测系统来探索暗物质和中微子的性质。我们为在CERN大型Hadron Collider的Atlas Project的持续运行做出了贡献。我们已经构建了和委托的电子系统以及驱动它们的软件。从数据开始，我们已经对外来粒子发挥了领先的作用，2012年发现了希格斯·波森（Higgs Boson）以及对顶级夸克（Top Quark）的性能的研究。我们大量投资于ATLAS探测器的升级，这将允许从2021年开始收集大型数据集。尽管从其引力相互作用中推断出的Darkmatter存在充分的间接证据，但它尚未在地面实验室中直接检测到。直接检测性培训试图观察目标检测到的暗物质散射。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是一个液体氩检测器，具有针对多吨质量的独特潜力，并具有DMTPC检测器开发程序，以测量暗物质风，以及Lux-Zeplinexperiment。该小组在高压TPC方面的专业知识现在正在被验证，以进行与Hyper-K实验的中性共鸣一部分相关的测量。使用与我们的暗物质研究类似的检测技术，我们还参与了围绕宇宙中抗物质不对称的难题的难题。我们测量了Lepton部门的CP违规行为，从而在日本进行了T2K长的基线中微子实验。我们的加速器科学专业知识将使我们能够为高光度LHCAND ILC的机器 - 探测器界面提供远程研究。我们还将扩大我们的苯酚学组与实验性中微子和暗物质社区之间的相互作用。
