Experimental Particle Physics

三年的时间尺度特别令人兴奋，因为LHC可能即将发现希格斯粒子，并作为升级计划的一部分开辟新的能源前沿：我们将集中精力分析、发现和解释希格斯粒子，并在CP破坏和罕见的B衰变中寻找新的物理学。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LHC计划，我们的战略是从两个实验（ATLAS和LHCb）产生领先的物理结果，基于这些实验以及CDF的专业知识。我们将根据我们目前的专业知识，为ATLAS提供及时的希格斯极限设置和发现的第一个结果。在确保高质量完成CDF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，我们将发现罕见的二体B衰变，寻找粲中的CP破坏，并利用早期的数据样本对Bs扇区的CP破坏进行精确测量。从长远来看，我们将从环介导的过程中测量CKM角γ，这提供了重要的新物理灵敏度。我们继续投资并推动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物理学中的影响力，并促进新领域，如NA 62和线性对撞机。我们还通过苏格兰资助理事会（SFC）和学院在这些领域的杠杆支持。我们已经建立了ATLAS和LHCb的物理分析流，使用网格，并将继续充分利用2011-12 LHC数据。我们还将继续参与我们发挥领导作用的长期举措。我们目前参与LHCb升级，ATLAS-FP计划，超级LHC强度升级和未来中微子计划。我们期待更多的参与工作，视大型强子对撞机的发现而定。在未来三年内，我们将发展这些领域，并在早期投资将产生最大效益的领域取得进展，与LHC物理开发的最高优先级保持一致。这将确保我们能够通过大量资金支持LHC升级计划（称为SUPA-LHC）来满足我们在硅探测器开发方面的优先事项。我们预计投资80万英镑的设备，与IGR平分，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。我们相信，在英国粒子物理学发展的关键时刻，相关的额外努力将是必不可少的。

The three-year timescale is particularly exciting with the possibility of imminent Higgs discovery at the LHC and the opening of a new energy frontier as part of the upgrade programme: we will focus our efforts on Higgs analysis, discovery and interpretation, and the search for new physics in CP violation and rare B decays. 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 two experiments (ATLAS and LHCb) based upon expertise developed in those experiments as well as from CDF. We will provide timely first results in Higgs limit setting and discovery for ATLAS, based upon our current expertise. Having secured high-quality completion on CDF, where we set earlier limits in the Higgs analyses, 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 discover rare two body B decays, search for CP violation in charm and make precison measurements of CP violaton in the Bs sector with early data samples. In the longer term we will measure the CKM angle gamma from loop-mediated processes which offer significant new physics sensitivity.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 NA62 and the linear collider. We additionally lever support through Scottish Funding Council (SFC) and the College in these areas. We have set up physics analysis streams for ATLAS and LHCb, using the Grid, and will continue to fully exploit the 2011-12 LHC data. We will also maintain our involvement in longer-term initiatives where we have leadership roles. We presently participate in the LHCb upgrade, the ATLAS-FP initiative, the super-LHC intensity upgrades and future neutrino initiatives. We anticipate greater involvement in work, contingent upon discoveries made at the LHC. Over the next three years we will develop these areas and progress those where early investment will become most productive, consistent with the highest priority of LHC physics exploitation.To enhance the priority programme, we will gain through the second phase of SUPA. This will ensure that we can meet our priorities in silicon detector development via substantial funding in support of the LHC upgrade programme, known as SUPA-LHC. We anticipate investing £800k in equipment, shared equally with the IGR where we gain from joint facilities. This strategy is well suited to the skills and capacity of our core group. We believe the associated additional effort will be essential at a critical point in the evolution of UK particle physics.
