CAREER:Research in Particle Physics with CMS

该奖项由2009年《美国复苏和再投资法案》(公法111-5)资助。这份职业建议书描述了一项研究计划，该计划将利用紧凑型Muon螺线管(CMS)探测器探索欧洲核子研究中心大型强子对撞机(LHC)的新发现机会。在14TeV的pp碰撞下，大型强子对撞机有望为基本粒子物理现象打开一扇巨大的新窗口。这项工作的学术价值包括对希格斯粒子或其他可能出现在标准模型扩展中的新粒子的探索，以及对像素探测器的理解。这里提出的研究计划是一个三管齐下的计划，通过研究轻子通道中的轻希格斯粒子来探索超越标准模型的物理，参与CMS像素探测器的调试、校准和操作，以及开发CMS跟踪的升级策略。发现希格斯玻色子并随后探索其性质是CMS实验的关键目标。这在实验上具有挑战性，需要详细了解探测器的性能，特别是像素顶点探测器的性能。这项提议的更广泛影响包括给当地社区大学的教职员工和学生带来实验粒子物理的兴奋和挑战。作为粒子物理学本科课程的一部分，康奈尔大学的学生分析CLEO数据的试点项目非常成功。这里描述的计划是真正的变革性的。校长调查员进一步开发了这些工具，并将其提供给当地更广泛的两年制小型社区学院，从而为教师和参与其中的学生提供适当的培训，使他们能够参与实际的数据分析。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This CAREER proposal describes a research program that will explore the opportunities for new discoveries at the Large Hadron Collider(LHC) at CERN using the Compact Muon Solenoid(CMS) detector. With pp collisions at 14 TeV, the LHC is expected to open a vast new window on elementary particle physics phenomena. The intellectual merit of this work includes the exploration of the Higgs particle or of other new particles that could appear in extensions of the Standard Model, as well as the understanding of the pixel detector. The research program presented here is a three-pronged plan to explore beyond-the-Standard-Model physics by studying the light Higgs particle through tau lepton channels, to participate in the commissioning, calibration, and operation of the CMS pixel detector, and to develop upgrade strategies for CMS tracking. Discovery of the Higgs boson and the subsequent exploration of its properties are key goals of the CMS experiment. This is experimentally challenging and requires a detailed understanding of the detector performance, particularly of the pixel vertex detector. The broader impact of this proposal includes bringing the excitement and challenges of experimental particle physics to faculty and students at local community colleges. A pilot program with Cornell students analyzing CLEO data as part of an undergraduate course in particle physics has been very successful. The program described here is truly transformational. The Principle Investigator further develops these tools and makes them available to a broader community of small local 2-year community colleges, thereby providing suitable training for both the teaching faculty and the students involved, so they can participate in actual data analysis.
