Experimental Particle Physics: Equipment Request to the STFC Particle Physics Grants Panel: Addendum to the Consolidated Grant Award (ST/N000358/1)

随着LHC Run 2中新能源前沿的开放，四年的时间表特别令人兴奋。我们将集中精力在Higgs和ATLAS的顶级部门，NA 62的K介子部门以及LHCb的魅力和美容部门寻找BSM过程。我们同时进入了一个主要的建设阶段，在我们的ATLAS，LHCb和ILC探测器开发之间建立了协同作用。我们预计，MICE将证明电离冷却是迈向中微子工厂的重要一步，日本将与国际社会一起决定建造ILC。我们已经发展了探测器的开发和建造能力，以促进这一未来的计划，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。所有学者都积极参与LHC计划，我们的战略是从三个实验（ATLAS，LHCb和NA 62）中产生领先的物理结果，基于这些实验中开发的专业知识。我们将根据我们目前的专业知识，及时为ATLAS提供Higgs H->bb模式的第一个结果。在第1轮中获得高质量的完成后，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，我们将测量罕见的两体B衰变，寻找在粲CP破坏和精确测量CP破坏的Bs部门。我们将测量CKM角γ从环介导的过程，提供了显着的新的物理灵敏度。我们将进行新的测量，并在粲重子和激发美介子的光谱中寻找新的状态。对于NA 62，我们将保持英国在测量K介子衰变与电子和μ介子的比率方面的专业知识，建立K介子和π介子衰变比率的测量和寻找暗光子。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，并促进线性对撞机等新领域的发展。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LHC物理开发的最高优先级相一致。为了加强优先计划，我们将通过苏格兰大学物理联盟（SUPA）提供支持。这将确保我们能够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。

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.
