Completion of the CLEO-c Experiment

CLEO的合作导致了实验魅力物理学的复兴，这正在扩大这一学科的前沿和我们对重味道物理的知识。CLEO在魅力衰变测量方面取得了前所未有的精度和范围，这得益于魅力阈值区域前所未有的数据样本和出色的探测器。CLEOc探测器是在这个能量区域运行的任何其他探测器都无法超越的，它是唯一适合研究魅力产生和衰变的探测器。康奈尔大学的初级粒子物理实验室(Lepp)主办了CLEOc实验，在过去的五年里，它已经收集了接近魅力产生阈值的数据。该提案要求提供三年的资金，以使清洁发展组织的协作能够完成对这些数据的分析和公布。这一提议的智力价值来自于它对重味物理学和QCD的潜在影响。这些结果将极大地扩展对重口味物理学的影响和理解，使世界能够从对CLEOc、Babar、Belle、LHCb和Tevatron的投资中获益。此外，这一提议有可能使许多其他测量成为可能，这些测量将加深我们对D和DS介子现象学的理解，并将极大地促进探测微扰和非微扰QCD的Charmonium和Upsilon物理。这项提议的更广泛的影响包括广泛的LEPP教育推广计划和一项新的倡议。每年有1000多名参观者参观该实验室，500多人参加其年度开放参观。实验室工作人员还将他们的科学带到学校，远至纽约市，接触到服务不足的学生，他们还参与了帮助初中和高中教师开发现代物理课程材料的项目。该实验室举办了一项面向本科生的研究体验项目，吸引了底特律韦恩州立大学约三分之一的学生。与这项提议相关的是，勒普计划发起一项新的倡议，夸克活着！，该计划将为本科生提供简单的CLEO-c数据分析项目。CLEOc DD数据因其简单的事件拓扑和高重建效率而非常适合于此目的。该包将通过WWW访问，其中将包括一份项目清单和执行这些项目所需的所有工具，包括软件和蒙特卡洛样本。一旦夸克还活着！已经在本科生中实施，一个高中教师团队将评估是否有可能将其改编成适用于高中生。

The CLEO Collaboration has led a renaissance in experimental charm physics that is expanding the frontiers of the subject and our knowledge of heavy flavor physics. The precision and reach in charm decay measurements achieved by CLEO are due to unprecedented data samples in the charm threshold region and an excellent detector. The CLEOc detector is unsurpassed by any other detector that has operated in this energy region and it is uniquely suited for studying charm production and decay.Cornell's Laboratory for Elementary Particle Physics (LEPP) hosts the CLEOc experiment, which over the last five years, has collected data near the charm production threshold. This proposal presents a request for three years of funding to allow the CLEO collaboration to complete analyses and publication of these data. The Intellectual Merit of this proposal is derived from its potential impact on heavy flavor physics and QCD. These results will substantially extend the reach and understanding of heavy flavor physics, allowing the world to reap the benefits of investments in CLEOc, BaBar, Belle, LHCb and the Tevatron. Also, this proposal has the potential to enable numerous other measurements that will deepen our understanding of D and Ds meson phenomenology and will substantially advance charmonium and upsilon physics, which probe perturbative and non-perturbative QCD. The Broader Impact of this proposal includes the extensive LEPP program of educational outreach and a new initiative. Each year, more than 1000 visitors tour the Laboratory and more than 500 attend its annual open house. Laboratory personnel also bring their science to the schools, traveling as far as New York City to reach underserved students, and they participate in programs that help middle and high school teachers develop course material on modern physics. The Laboratory hosts a Research Experience for Undergraduates program, which draws about one -third of its students from Wayne State University in Detroit. In connection with this proposal, LEPP plans to launch a new initiative, Quarks Alive!, that will provide simple CLEO-c data analysis projects for undergraduates. CLEOc DD data are ideally suited to this purpose because of their simple event topology and high reconstruction efficiency. The package, which will be accessible via the WWW, will include a list of projects and all the tools needed to carry them out, including software and Monte Carlo samples. Once Quarks Alive! has been implemented for undergraduates, a team of high school teachers will evaluate possibilities for adapting it for high school students.
