以下信息复制自RHUL小组2015年的综合拨款申请：实验粒子物理学解决了一些关于宇宙在最小物质粒子、夸克和轻子水平上的结构和行为以及它们之间的作用力的基本问题。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。我们正在为2015年开始的新数据采集做准备，对这些和相关主题进行进一步的分析。尽管有充分的间接证据表明暗物质的存在是从其引力相互作用中推断出来的，但它还没有在地面实验室中被直接探测到。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/CLEAN的世界领先的暗物质搜索来探索这些问题，DEAP/CLEAN是一种具有独特的定标到数吨质量的液体Ar探测器，DMTPC探测器开发计划来测量暗物质风，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Hyper-K实验中中微子研究相关的测量。我们在加速器科学方面的专业知识将使我们能够为高光度LHC和ILC开展机器与探测器接口的研究。我们还将扩大我们的现象学小组和实验社区之间的互动。

The following information is reproduced from the RHUL Group's2015 Consolidated Grant application: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 preparing for therenewed data taking starting in 2015 with further analyses on theseand related topics.Although there is ample indirect evidence for the existence of darkmatter is 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/CLEAN, 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.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 community.
