The four-year timescale is particularly exciting with the exploitation of the LHC and upgrade developments reaching a peak. 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, 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 anticipate a significant transition in the neutrino sector. We finalised data taking in MICE, with a demonstration of ionization cooling imminent, and 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 at a key point in the European decision-making process. We have developed detector development and construction capacity to contribute to this 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.All 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 1 and provided timely first Run-2 results in Higgs H->bb modes and top production for ATLAS, we will ensure that this experience will underpin future ATLAS publications. Based on our earlier work, we will be key players in answering questions concerning the origin of mass and the nature of CP violation. 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 expertise and will lead 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 College 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 2 data. We will also maintain our involvement in longer-term initiatives where we have leadership roles. We presently have leading roles in the ATLAS and LHCb upgrades, the linear collider and future neutrino initiatives. We anticipate greater involvement in these forward-looking programmes, based upon discoveries made at the LHC. 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 physics exploitation.To enhance the priority programme, we have invested in generic detector developments leading to significant impact in sensors technologies. 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达到顶峰，四年的时间尺度特别令人兴奋。我们将把我们的努力集中在ATLAS的希格斯和顶级部门，NA62的Kaon部门，以及LHCb的魅力和美容部门，包括在每个案例中搜索BSM过程。我们正在同时进入一个重要的建设阶段，这将需要大量的努力，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效应基础上。我们预计中微子领域将发生重大转变。我们最终完成了老鼠的数据采集，电离冷却的演示即将到来，我们已经加入了T2K合作，通过WAGASCI/BabyMind探测器为其近探测器的升级做出了贡献，作为迈向未来中微子发展的重要一步。与国际社会一道，我们将为在欧洲决策过程的关键时刻建立未来直线对撞机所需的领导做出贡献。我们已经发展了探测器的开发和建造能力，以促进这一计划，并以精心规划的方法建立了我们的技术人员和工程工作。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，我们正处于这些领域所需发展的前沿。所有学者都积极参与CERN计划，我们的战略是根据ATLAS、LHCb和NA62实验中发展的专业知识，产生尖端的物理结果。我们确保了第一轮的高质量完成，并及时提供了Higgs H-&>BB模式的第一轮-2结果和ATLAS的顶级制作，我们将确保这种经验将为未来的ATLAS出版物奠定基础。在我们早期工作的基础上，我们将在回答有关质量起源和CP违规性质的问题时发挥关键作用。对于LHCb，我们将测量环状和树状B衰变的CKM角伽马，寻找CP破坏，并测量Charm衰变中的混合参数。我们将探索双重魅力重子的光谱，并测量所发现的态的性质。对于NA62，我们将保持英国的专业知识，并将领导对K-&>pi，nu，nu通道的分析。我们将继续投资并促进世界级探测器开发活动，以实现更长期的倡议，我们的网格优势旨在最大化我们在大型强子对撞机物理领域的影响，并促进新的领域，如线性对撞机。此外，我们还通过学院在这些领域提供了重要支持。我们已经使用网格为每个实验建立了物理分析流，并将继续充分利用LHC Run 2数据。我们还将继续参与我们发挥领导作用的较长期计划。我们目前在ATLAS和LHCb升级、线性对撞机和未来的中微子倡议方面处于领先地位。根据大型强子对撞机的发现，我们预计会更多地参与这些前瞻性计划。在接下来的四年里，我们将发展这些领域，并在早期投资将变得最有成效的领域取得进展，这与我们对大型强子对撞机物理开发的最优先事项保持一致。为了加强优先计划，我们投资于对传感器技术产生重大影响的通用探测器开发。这确保了我们能够保留专业知识，以便通过支持大型强子对撞机升级和其他计划来实现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，在那里我们从联合设施中获益。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至关重要的。
