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.

四年的时间表特别令人兴奋，因为LHC的开发和升级发展达到了顶峰。我们将把我们的努力集中在Higgs和ATLAS的顶级部门，NA 62的K介子部门，以及LHCb的魅力和美容部门，包括在每种情况下搜索BSM过程。我们同时进入了一个主要的建设阶段，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作用。我们预计中微子领域将发生重大转变。我们完成了MICE的数据采集，电离冷却的演示即将到来，我们加入了T2 K合作，通过WAGASCI/BabyMind探测器为其近探测器升级做出了贡献，这是朝着未来中微子发展迈出的重要一步。我们将与国际社会一起，在欧洲决策过程的关键时刻，为建立未来的线性对撞机所需的领导力做出贡献。我们已经发展了探测器的开发和建造能力，以促进这一方案，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，良好校准的探测器，增加的计算能力和理论输入将是必不可少的，我们在这些领域所需的发展的最前沿。所有的学者都积极参与了欧洲核子研究中心的计划，我们的战略是根据这些实验中开发的专业知识，从ATLAS，LHCb和NA 62产生领先的物理结果。在确保运行1的高质量完成并及时提供Higgs H->bb模式下的第一个运行2结果和ATLAS的顶级生产之后，我们将确保这一经验将成为未来ATLAS出版物的基础。基于我们早期的工作，我们将成为回答有关质量起源和CP破坏性质的问题的关键参与者。对于LHC B，我们将测量环和树主导的B衰变的CKM角γ，搜索CP破坏并测量粲衰变中的混合参数。我们将探索双粲重子的光谱，并测量所发现态的性质。对于NA 62，我们将保持英国的专业知识，并将领导K->pi，nu，nu通道的分析。我们将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Grid实力旨在最大限度地发挥我们在LHC物理学方面的影响力，并促进新领域，如线性对撞机。我们还杠杆通过大学在这些领域的重大支持。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2数据。我们还将继续参与我们发挥领导作用的长期举措。我们目前在ATLAS和LHCb升级，线性对撞机和未来中微子计划中发挥着主导作用。我们期望更多地参与这些前瞻性的计划，在大型强子对撞机的发现的基础上。在接下来的四年里，我们将发展这些领域，并在早期投资将成为最有成效的领域取得进展，这与我们的LHC物理开发的最高优先级相一致。为了加强优先级计划，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。这确保了我们能够保留专业知识，以便通过支持LHC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集团合作，我们将从联合设施中获益。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。
