The award will support the ongoing research program of Professor Stephen Reucroft with the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider (LHC). The group's main CMS hardware activity continues on the Electromagnetic Calorimeter (ECAL) avalanche photodiode (APD) readout. The group members are coordinators of the CMS electron reconstruction using particle flow techniques - building on the group tracker and ECAL expertise. The award will enable to group to continue their analysis effort working on Standard Model Higgs searches using leptonic final states - building on their electron reconstruction work. This proposal addresses the early discovery era of the LHC. The support will enable the group to work on CMS commissioning work and simultaneously develop electron reconstruction algorithms. These include recovery of bremsstrahlung photons and conversions in the Silicon Tracker and optimize the electron selection efficiency and purity. These tools will then apply to the direct search for the Higgs boson. This support is critical to the group's ability to exploit the considerable investment of more than a decade.The intellectual merit of the research is profound, addressing fundamental questions, such as the origin of mass. The chosen area of research, the search for the Higgs, is one of the most important analysis of the LHC startup. The broader impact supported by this award include possible technological spin-offs from the photo-detector work to medical physics, biophysics and quantum optics. The group is involved in educational outreach of a broad range of people from elementary school, high school, undergraduate and graduate students, to postdocs.

该奖项将支持Stephen Reucroft教授正在进行的研究计划，并在CERN的大型强子对撞机（LHC）的紧凑型MUON螺线管（CMS）实验。该小组的主要CMS硬件活动继续在电磁热量计（ECAL）雪崩光电二极管（APD）读数上继续进行。小组成员是使用粒子流技术的CMS电子重建的协调员 - 在组跟踪器和ECAL专业知识上建立。该奖项将使小组能够继续使用Leptonic最终状态进行标准模型HIGGS搜索工作 - 基于其电子重建工作。该建议涉及LHC的早期发现时代。支持将使小组能够从事CMS调试工作，并同时开发电子重建算法。其中包括恢复Bremsstrahung光子和硅跟踪器中的转换，并优化了电子选择效率和纯度。然后，这些工具将直接搜索Higgs Boson。这种支持对于该小组利用十多年来大量投资的能力至关重要。研究的智力优点是深刻的，解决了基本问题，例如弥撒的起源。研究的研究领域是对希格斯的搜索，是对LHC创业公司最重要的分析之一。该奖项支持的更广泛的影响包括从光检测器工作到医学物理，生物物理和量子光学的技术衍生产品。该小组参与了从小学，高中，本科生和研究生到Postdocs的广泛人士的教育宣传。
