Experimental particle physics addresses some of the fundamental questions about the structure and behaviour of the Universe at the level of the smallest particles of matter, the quarks and the leptons, and the forces acting between them. In this project we are contributing to the preparation of the ATLAS project at the Large Hadron Collider at CERN that will begin taking data in 2007. We are constructing and commissioning electronic systems and the software that drives them. From late 2007 we will be analysing the data as it becomes available. In particular we will be searhing the data for evidence of the existance of the Higgs boson, one of the key missing elements of the Standard Model of particle physics at present, and for supersymmetric particles, that are expected to exist. We are also planning to understand better the structure of the proton. In parallel we are are continuing our studies of data taken at the Stanford Linear Accelerator in California to measure the subtle difference in behaviour between particles and antiparticles that may be responsible for the existence of matter but no antimatter in the Universe. We are contributing to a major research and development programme for the construction of a linear collider - an accelerator that will collide electrons and positrons at very high energy. This machine, proposed by a worldwide collaboration, will be the highest energy electron-positron collider ever built. We are also carrying out a research and development programme on a detector to be used at this accelerator.

实验粒子物理学在最小的物质粒子、夸克和轻子以及它们之间的作用力的水平上解决了关于宇宙的结构和行为的一些基本问题。在这个项目中，我们正在为欧洲核子研究中心大型强子对撞机的ATLAS项目的筹备工作做出贡献，该项目将于2007年开始采集数据。我们正在建造和调试电子系统以及驱动它们的软件。从2007年底开始，我们将在数据可用时对其进行分析。特别是，我们将搜索数据，以寻找希格斯玻色子存在的证据，希格斯玻色子是目前粒子物理标准模型中缺失的关键元素之一，以及预计将存在的超对称粒子。我们还计划更好地了解质子的结构。与此同时，我们正在继续对加州斯坦福直线加速器的数据进行研究，以测量粒子和反粒子之间行为的细微差异，这些差异可能是宇宙中存在物质而不是反物质的原因。我们正在为建造线性对撞机的重大研究和开发方案做出贡献--这是一种将以非常高的能量对撞电子和正电子的加速器。这台由全球合作提出的机器将是有史以来建造的能量最高的电子-正电子对撞机。我们还在研究和开发一种将用于该加速器的探测器。
