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.

CLEO合作引领了实验魅力物理的复兴，扩展了学科的前沿和我们对重味物理的认识。CLEO在粲数衰减测量中取得的精度和范围归功于前所未有的粲数阈值区域的数据样本和出色的检测器。CLEOc探测器是在该能量区域运行的任何其他探测器所无法超越的，它非常适合研究粲子产生和衰变。康奈尔大学的基本粒子物理实验室（LEPP）主持了CLEOc实验，在过去的五年里，收集了接近魅力产生阈值的数据。该提案提出了一项为期三年的资助请求，以允许CLEO合作完成这些数据的分析和出版。该建议的知识价值源于其对重味物理和QCD的潜在影响。这些结果将大大扩展重味物理的范围和理解，使世界从对CLEOc， BaBar, Belle， LHCb和Tevatron的投资中获益。此外，这一提议有可能实现许多其他测量，这些测量将加深我们对D和Ds介子现象学的理解，并将大大推进调和和厄普西隆物理学，它们将探测微扰和非微扰QCD。该提案的更广泛影响包括广泛的LEPP教育推广计划和一项新倡议。每年有超过1000名游客参观实验室，超过500人参加其年度开放日。实验室的工作人员也把他们的科学成果带到学校，最远到纽约市去接触那些得不到教育的学生，他们还参与了一些项目，帮助初中和高中教师编写现代物理学的课程材料。该实验室举办了一个本科生研究体验项目，吸引了底特律韦恩州立大学约三分之一的学生。针对这一提议，LEPP计划发起一项新的倡议——夸克活着！，为本科生提供简单的CLEO-c数据分析项目。CLEOc DD数据由于其简单的事件拓扑结构和高的重建效率而非常适合这一目的。这个包可以通过WWW访问，它将包括一个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示例。曾经的夸克还活着！已经在大学生中实施，一个高中教师小组将评估将其适用于高中生的可能性。
