The four-year timescale is particularly exciting with the opening of a new energy frontier in LHC Run 2. We will focus our efforts on searches for BSM processes in the Higgs and top sectors for ATLAS, in the kaon sector for NA62, and in the charm and beauty sector for LHCb. We are simultaneously entering a major construction phase where synergies have been established between our ATLAS, LHCb and ILC detector developments. We anticipate that MICE will demonstrate ionization cooling as a major step towards a neutrino factory and Japan, with the international community, will decide to build the ILC. We have developed detector development and construction capacity to contribute to this future 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 LHC programme and our strategy is to generate leading-edge physics results from three experiments (ATLAS, LHCb and NA62) based upon expertise developed in those experiments. We will provide timely first results in Higgs H->bb modes for ATLAS, based upon our current expertise. Having secured high-quality completion in Run 1, 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 rare two body B decays, search for CP violation in charm and make precision measurements of CP violation in the Bs sector. We will measure the CKM angle gamma from loop-mediated processes which offer significant new physics sensitivity. We will perform new measurements and search for new states in the spectroscopy of charmed baryons and excited beauty mesons. For NA62 we will maintain the UK expertise in measuring the ratio of kaon decays to electrons and muons, establish measurements of the ratio of kaon and pion decays and search for dark photons.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 will be supported via the Scottish Universities Physics Alliance (SUPA). This will ensure that we can meet our priorities in silicon detector development via support of the LHC upgrade and other programmes. We anticipate working with the IGR 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.

在LHC Run 2中开设新的能源边界2时，这四年的时间表尤其令人兴奋。我们将重点放在搜索Higgs和Atlas的BSM流程上，NA62的Kaon领域以及LHCB的Charm和Beauty领域。我们同时进入了一个主要的建筑阶段，在我们的ATLA，LHCB和ILC检测器开发之间建立了协同作用。我们预计，小鼠将证明电离冷却是迈向中微子工厂的重大一步，而日本和国际社会将决定建立ILC。我们已经开发了探测器的开发和建筑能力，以为这项未来的计划做出贡献，并采用精心计划的方法来建立我们的技术人员和工程工作。改进的分析技术，良好的检测器，计算能力的提高和理论输入将是必不可少的，我们处于这些领域所需发展的最前沿。所有学者都大量参与了LHC计划，我们的策略是基于这些实验的三个实验（ATLAS，LHCB和NA62）创建的三个实验的领先物理学结果。我们将根据我们当前的专业知识为Higgs H-> BB模式提供及时的首先结果。在运行1中获得了高质量的完成后，我们将确保这种经验将在未来的Atlas出版物中得到支持。根据我们较早的工作，我们将成为回答有关质量起源和违反CP的性质的问题的关键参与者。对于LHCB，我们将测量罕见的两个身体B衰变，以魅力搜索CP违规，并对BS部门的CP违规进行精确测量。我们将从循环介导的过程中测量CKM角γ，这些过程具有重要的新物理敏感性。我们将进行新的测量结果，并在Charmed Baryons和激动的美容媒介的光谱中寻找新状态。对于NA62，我们将维持英国在衡量Kaon衰变与电子和MUON的比率方面保持专业知识，建立对Kaon和Pion衰变比率的测量值，并寻找深色光子。我们继续投资并促进了世界一流的探测器开发活动，以启用长期的倡议，并促进我们的网格实力，以促进我们的竞争力，并促进了LHC的促进。我们还通过这些领域的大学提供了大力支持。我们使用网格为每个实验设置了物理分析流，并将继续完全利用LHC运行2个数据。我们还将保持参与我们担任领导角色的长期计划。目前，我们在Atlas和LHCB升级，线性对撞机和未来的中微子计划中扮演着领导角色。我们预计，根据LHC的发现，我们会更加参与这些前瞻性计划。在接下来的四年中，我们将开发这些领域，并进步那些早期投资将变得最富有成效的那些领域，这与我们最高的LHC物理利用优先级相一致。为了增强优先计划，我们将通过苏格兰大学物理联盟（SUPA）得到支持。这将确保我们可以通过支持LHC升级和其他程序来满足硅探测器开发的优先事项。我们预计与IGR合作，我们可以从联合设施中获得。该策略非常适合我们核心小组的技能和能力。相关的响应努力将在英国粒子物理发展的关键点至关重要。
