The Cambridge High Energy Physics Group focuses its research activities on experiments at high-energy accelerators, currently the Large Hadron Collider and the ATLAS and LHCb experiments at CERN, the neutrino experiment MicroBooNE, and the long-baseline neutrino experiment DUNE at Fermilab, and future collider facilities. The goal is to understand the fundamental particles of nature and their interactions, in particular, to discover physics beyond our current understanding, to understand why the Universe is made only of matter and not antimatter and to reveal the identity of dark matter. The Group is also central to the multi-disciplinary Quantum Technologies for Fundamental Physics projects, AION and MAGIS, which use novel atom interferometry to detect and identify sources of dark matter and gravitational waves in the Universe.This grant will enable the group to fully exploit the physics of the LHC, to deliver our commitments to the current upgrades of the ATLAS and LHCb experiments, to prepare for the future upgrades of ATLAS and LHCb, to consolidate our strong participation in our neutrino programme, to deliver our commitments and exploit the first physics from the AION project and MAGIS experiment, and to undertake generic hardware research and development. The opportunities offered by this exciting physics programme will not only drive the forefront of discovery, but also provide substantial impact to local enterprises and on public engagement.

剑桥高能物理组的研究活动主要集中在高能加速器上的实验，目前是欧洲核子研究中心的大型强子对撞机和ATLAS和LHCb实验，中微子实验MicroBooNE，费米实验室的长基线中微子实验DUNE，以及未来的对撞机设施。我们的目标是了解自然界的基本粒子及其相互作用，特别是发现超越我们目前理解的物理学，了解为什么宇宙只由物质而不是反物质组成，并揭示暗物质的身份。该小组也是基础物理学多学科量子技术项目AION和MAGIS的核心，这些项目使用新型原子干涉测量法来探测和识别宇宙中暗物质和引力波的来源。这笔赠款将使该小组能够充分利用LHC的物理学，履行我们对ATLAS和LHCb实验的升级承诺，为ATLAS和LHCb的未来升级做准备，巩固我们在中微子计划中的强大参与，履行我们的承诺并利用AION项目和MAGIS实验的第一个物理学，并进行通用硬件研究和开发。这个令人兴奋的物理学计划提供的机会不仅将推动发现的前沿，而且还将对当地企业和公众参与产生重大影响。
