实验粒子物理学解决有关宇宙的结构和行为的基本问题，在物质的最小粒子，夸克和轻子的水平，并在最大的宇宙学尺度，努力发现暗物质的性质。我们正在大型强子对撞机（LHC）上探索粒子的基本性质，开发未来的粒子加速器，用新型粒子探测器寻找暗物质，并开发解释这些数据所需的理论，激发粒子物理学的新方向。我们正在为欧洲核子研究中心（CERN）大型强子对撞机上的ATLAS项目做出贡献，该项目最近发现了希格斯玻色子。我们已经为探测器和驱动它们的软件构建并调试了电子系统，现在专注于数据分析。特别是，我们致力于测量希格斯玻色子的性质，直到最近，希格斯玻色子仍然是目前粒子物理学标准模型的关键缺失元素之一，并寻找超对称粒子和其他奇异现象，这些现象预计会存在。我们还致力于数据分析，以更好地了解顶夸克的性质和质子的结构。征服粒子物理学的高能前沿需要新的加速器科学。我们正在开发先进和新颖的加速器技术，提供加速器技术的专业知识，研究，开发和培训，并促进科学和社会中的先进加速器应用。具体而言，我们开发新的电子加速器诊断，如激光线横向发射度测量装置，谐振腔束流位置监测器和束流产生的辐射监测和应用。我们还参与了各种致力于实现高能线性对撞机和新型激光等离子体加速技术的研究。我们还在开发最先进的软件来模拟高能加速器中的束流损失，并将其应用于当前的LHC操作和未来的LHC升级。宇宙学测量确定暗物质构成宇宙能量密度的五倍以上，而我们所知道的粒子。虽然暗物质的存在是从它的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暗物质在目标探测器核上的散射。为了探索这些基本问题，我们成立了一个新的暗物质小组，参与世界领先的DEAP/CLEAN暗物质搜索，DEAP/CLEAN是一种具有独特潜力的液态氩探测器，可扩展到数吨质量，并与DMTPC探测器开发计划一起测量暗物质风，它可以将暗物质引起的反冲信号与地球通过银河系暗物质晕的运动相关联。

Experimental particle physics addresses 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 at the largest cosmological scales, striving to discover the nature of dark matter. We are exploring fundamental properties of particles at the Large Hadron Collider (LHC), developing the particle accelerators of the future, searching for dark matter with new kinds of particle detectors, and developing the theory needed to interpret this data and motivate new directions in particle physics.We are contributing to the ATLAS project at the Large Hadron Collider at CERN, which recently discovered the Higgs boson. We have constructed and commissioned electronic systems for the detector and the software that drives them, and now focus on data analysis. In particular, we work on measuring the properties of the Higgs boson, which until recently was one of the key missing elements of the Standard Model of particle physics at present, and on searches for supersymmetric particles and other exotic phenomena, that are expected to exist. We also work on data analyses to understand better the properties of the top quark and the structure of the proton.Conquering the high energy frontier in particle physics requires new accelerator science. We are developing advanced and novel accelerator technology, providing expertise, research, development and training in accelerator techniques, and promoting advanced accelerator applications in science and society. Specifically, we develop novel electron accelerator diagnostics, such as laser-wire transverse emittance measurement devices, resonant cavity beam position monitors and beam generated radiation monitoring and applications. We are also involved with various studies devoted to the realisation of a high energy linear collider, and novel Laser-Plasma acceleration technology. We are also developing state of the art software to simulate beam losses in high energy accelerators and will apply these to current LHC operations and LHC upgrades for the future.Cosmological measurements determine that dark matter makes up five times more of the energy density of the universe than the particles we know of. Although the existence of dark matter is inferred from its gravitational interactions, it has not yet been directly detected in terrestrial laboratories. Direct detection experiments seek to observe dark matter scattering on target detector nuclei. To explore these fundamental issues, we have set up a new dark matter group to participate in a world-leading dark matter search on DEAP/CLEAN, a liquid Argon detector with unique potential for scaling to multi-tonne masses, and with the DMTPC detector development program to measure the dark matter wind, which can correlate a dark matter-induced recoil signal with the earth's motion through the galactic dark matter halo.
