High Energy Physics Research with Collider Experiments

该提案要求资金支持堪萨斯大学（KU）的研究和教育推广。KU实验粒子物理小组提出了一个广泛的研究计划，通过他们参与DZero实验，该实验现在正在费米实验室的Tevatron中获取质子-反质子碰撞数据，以及CLEO实验，该实验现在正在康奈尔CESR设施中获取电子-正电子碰撞数据。DZero分析包括测量W- z截面比、W- b-bar截面和单顶截面；对丢失能量事件的调查，以及受希格斯启发的对tau-pair产生的研究。DZero正在以最高的能量获取数据，这个实验有重大发现的可能性很大。例如，一个大的单顶或希格斯到陶对的横截面可能是一个超越标准模型的物理信号，比如超对称。有了CLEO，该小组将继续发表其本科生研究人员所做的物理分析。堪萨斯大学小组已经发表了五篇CLEO期刊文章，主要作者是本科生，并有几项正在进行的分析将在这个项目中进行。这项工作主要集中在窄Upsilon共振的光子衰减，这是CLEO保持最佳数据样本的丰富物理领域。一旦CLEO-c计划在粲光阈值附近积累了足够的数据，该小组将研究粲光ium直接产生光子。KU小组正在建造CMS探测器，并为线性对撞机探测器做开发工作。有了CMS，该小组利用从DZero硅探测器获得的专业知识，帮助美国在硅跟踪器外桶探测器上的努力。KU集团在费米实验室维护试验台和测试监督。它将在本提案的最后一年协助探测器的调试工作。CMS计划在提案期结束时开始收集数据。线性对撞机探测器研发将专注于研究热测量方案。在教育/拓展领域，pi致力于1)继续我们的QuarkNet中心，现在已经是第四年了，它促进了与地区高中物理教师的研究和教育项目；2)制作一个教育卡通，通过赋予每一个令人难忘的动画个性，向学校的孩子们传授各种类型的夸克和轻子。较小的拓展项目包括参加大学开放日活动和帮助小学生进行科学展览。该研究项目非常适合培养本科生、研究生和博士后水平的学生。通过有数据要分析的项目，正在构建的项目和正在设计的项目，该小组可以在实验学科方面为学生提供全方位的培训。KU集团一直保持着通过面向不同群体的网站在互联网上传播研究成果的记录。

This proposal requests funds to support both research and education outreach at The University of Kansas (KU). The KU experimental particle physics group proposes a broad-based program of research through their involvement in the DZero Experiment, which is now taking proton-antiproton collision data at the Fermilab Tevatron, and in the CLEO Experiment, which is now taking electron-positron collision data at the Cornell CESR facility. DZero analyses being pursued include measurements of the W-to-Z cross section ratio, W b b-bar cross section, and single top cross section; an investigation of events with missing energy, and a Higgs-inspired study of tau-pair production. DZero is taking data at the highest energy and the potential for an important discovery with this experiment is great. For example, a large single top or Higgs to tau-pair cross section could be a signal for physics beyond the Standard Model, such as supersymmetry. With CLEO, the group will continue publishing physics analyses done by its undergraduate researchers. The KU group has published five CLEO journal articles with undergraduate principal authors and has several ongoing analyses that will be pursued in this project. This work mainly focuses on photon decays of the narrow Upsilon resonances, a rich area of physics where CLEO maintains the best data sample. Once the CLEO-c program accumulates sufficient data near the charm threshold, the group will study direct photon production from charmonium. The KU group is building the CMS detector and doing development work for a linear collider detector. With CMS, the group uses expertise gained with the DZero silicon detector to help the U.S. effort on the silicon tracker outer-barrel detector. The KU group maintains test stands and testing oversight at Fermilab. It will assist in the commissioning of the detector during the final year of this proposal. CMS is scheduled to begin taking data near the end of this proposal period. Linear collider detector R&D will focus on studying calorimetry options. In the education/outreach area, the PIs are committed to 1) the continuation of our QuarkNet center, now in its fourth year, that fosters research and education projects with area high school physics teachers and 2) the production of an educational cartoon that will teach school children about the various types of quarks and leptons by giving each a memorable animated personality. Smaller outreach projects include participation in university open house events and helping with science shows for grade school children. The research program is well suited to the training of students at the undergraduate, graduate and postdoctoral levels. By having projects with data to analyze, projects being built, and projects being designed, the group can give its students a full range of training in the experimental discipline. The KU group maintains its record of disseminating research findings via the Internet with web sites aimed at different communities.
