The next four-year timescale is particularly exciting with the exploitation of the LHC and upgrade developments at a critical stage. We will focus our efforts in the Higgs and top sectors for ATLAS, in the kaon sector for NA62, and in the charm and beauty sector for LHCb and in the neutrino sector at T2K and Hyper-K, including searches for BSM processes in each case. We are simultaneously entering a major construction phase which will require significant effort, building upon the synergies established between our ATLAS, LHCb and Linear Collider detector developments. We have undergone a significant transition in the neutrino sector where we have joined the T2K collaboration, contributing to its near detector upgrade through the WAGASCI/BabyMIND detectors, as a major step towards future neutrino developments. With the international community, we will contribute to the leadership needed to establish a future Linear Collider as part of the 2020 European strategy. We have developed detector development and construction capacity to contribute to our programme and have built up our technician and engineering effort in a carefully planned approach. Improved analysis techniques, well-calibrated detectors, increased computing power and theoretical input will be essential and we are at the forefront of the required developments in these areas.Most academics are heavily involved in the CERN programme and our strategy is to generate leading-edge physics results from ATLAS, LHCb and NA62 based upon expertise developed in those experiments. Having secured high-quality completion in Run 2 with significant results in Higgs H->bb modes and top production for ATLAS, we will exploit this experience to lead future ATLAS publications. Taking advantage of our work on boosted topologies and exploiting the larger Run 3 dataset, we will explore more extreme regions of phase space and use theoretical input to guide the interpretation of our results. For LHCb, we will measure the CKM angle gamma from loop and tree dominated B decays, search for CP violation and measure mixing parameters in charm decays. We will explore the spectrum of doubly-charmed baryons and measure the properties of the discovered states. For NA62 we will maintain UK computing expertise and will contribute to the analysis of the K->pi nu nu channel.We continue to invest in and promote a world-class Detector Development activity to enable longer-term initiatives and our Grid strength is aimed at maximising our impact in LHC physics as well as promoting new areas such as the linear collider. We additionally lever significant support through the University in these areas. We have set up physics analysis streams for each experiment, using the Grid, and will continue to fully exploit the LHC Run 3 data. We will also develop our involvement in longer-term initiatives exploiting our leadership roles. We presently have leading roles in the ATLAS and LHCb upgrades, the linear collider and future neutrino initiatives, such as T2K upgrades and Hyper-K. Over the next four years we will develop these areas and progress those where early investment will become most productive, consistent with our highest priority of LHC and neutrino physics exploitation. To enhance the priority programme, we have invested in generic detector developments leading to significant impact in sensors technologies. We have developed new capabilities in flip-chip bonding and chip design, complemented our well established core expertise. This has ensured that we can retain expertise in order to meet our priorities in silicon detector development via support of the LHC upgrade and other programmes. We anticipate working with the IGR and JWNC groups where we gain from joint facilities. This strategy is well suited to the skills and capacity of our core group. The associated responsive effort will be essential at a critical point in the evolution of UK particle physics.

随着大型强子对撞机的开发和升级发展处于关键阶段，未来四年的时间表尤其令人兴奋。我们将集中精力研究ATLAS的希格斯粒子和顶级扇区，NA62的kaon扇区，LHCb的魅力和美丽扇区以及T2K和Hyper-K的中微子扇区，包括在每种情况下搜索BSM过程。我们正在同时进入一个主要的建设阶段，这将需要巨大的努力，建立在我们的ATLAS， LHCb和线性对撞机探测器开发之间建立的协同作用之上。我们在中微子领域经历了重大转变，我们加入了T2K合作，通过WAGASCI/BabyMIND探测器为其近距离探测器升级做出了贡献，这是迈向未来中微子发展的重要一步。作为2020年欧洲战略的一部分，我们将与国际社会一道，为建立未来的线性对撞机提供所需的领导。我们发展了探测器的开发和建造能力，为我们的方案作出贡献，并以精心规划的方式建立了我们的技术人员和工程努力。改进的分析技术、校准良好的探测器、增加的计算能力和理论投入将是必不可少的，我们处于这些领域所需发展的前沿。大多数学者都积极参与欧洲核子研究中心的项目，我们的战略是根据在这些实验中发展的专业知识，从ATLAS、LHCb和NA62中产生领先的物理结果。在第2次运行中获得了高质量的完井，在Higgs H- b> bb模式和ATLAS的顶级生产中取得了显著成果，我们将利用这一经验来领导未来的ATLAS出版物。利用我们在增强拓扑上的工作和利用更大的Run 3数据集，我们将探索相空间的更极端区域，并使用理论输入来指导我们的结果的解释。对于LHCb，我们将从环和树主导的B衰变中测量CKM角伽玛，寻找CP违背并测量粲数衰变中的混合参数。我们将探索双粲重子的光谱，并测量所发现状态的性质。对于NA62，我们将保持英国的计算专业知识，并将对K->pi nu nu通道的分析做出贡献。我们继续投资和促进世界级的探测器开发活动，以实现长期计划，我们的网格实力旨在最大限度地提高我们在大型强子对撞机物理方面的影响，并促进线性对撞机等新领域的发展。此外，我们还通过大学在这些领域提供重要支持。我们已经为每个实验建立了物理分析流，使用网格，并将继续充分利用LHC运行3的数据。我们还将利用我们的领导角色，参与更长期的计划。我们目前在ATLAS和LHCb升级、线性对撞机和未来的中微子计划（如T2K升级和Hyper-K）中发挥主导作用。在接下来的四年里，我们将开发这些领域，并推进那些早期投资将成为最有成效的领域，与我们对大型强子对撞机和中微子物理开发的最高优先级保持一致。为了加强优先计划，我们投资于通用探测器的开发，从而对传感器技术产生重大影响。我们在倒装芯片键合和芯片设计方面开发了新的能力，补充了我们成熟的核心专业知识。这确保了我们可以保留专业知识，以便通过支持大型强子对撞机升级和其他计划来满足我们在硅探测器开发方面的优先事项。我们期待与IGR和JWNC小组合作，从联合设施中获益。这一战略非常适合我们核心团队的技能和能力。在英国粒子物理学发展的关键时刻，相关的响应努力将是必不可少的。
