High Energy Physics Research with Collider Experiments

这项提案要求资金支持堪萨斯大学(KU)的研究和教育推广。KU实验粒子物理小组通过参与DZero实验和CLEO实验提出了一个基础广泛的研究计划，DZero实验现在正在费米实验室Tevatron获取质子-反质子碰撞数据，CLEO实验现在正在康奈尔CESR设施获取电子-正电子碰撞数据。正在进行的DZero分析包括W-Z横截面比、W b b-bar横截面和单顶横截面的测量；对丢失能量的事件的调查；以及由希格斯启发的对tau对产生的研究。DZero正在以最高的能量获取数据，这项实验的重要发现的潜力是巨大的。例如，一个大的单顶或希格斯对Tau对的横截面可能是超越标准模型的物理信号，比如超对称性。有了CLEO，该组织将继续发表其本科生研究人员所做的物理分析。KU小组已经与本科生主要作者一起发表了五篇CLEO期刊文章，并有几个正在进行的分析，将在这个项目中进行。这项工作主要关注窄的Upsilon共振的光子衰变，这是CLEO保持最佳数据样本的一个丰富的物理领域。一旦CLEO-c计划在魅力阈值附近积累了足够的数据，该小组将研究从碳素直接产生光子。KU小组正在建造CMS探测器，并从事线性对撞机探测器的开发工作。通过CMS，该小组利用在DZero硅探测器方面获得的专业知识来帮助美国在硅跟踪器外筒探测器上的努力。KU集团在Fermilab维护测试台和测试监督。它将协助探测器在本提案的最后一年投入使用。CMS计划在此建议期接近尾声时开始采集数据。线性对撞机探测器的研发将专注于研究量热法的选择。在教育/推广领域，PI致力于1)继续我们的QuarkNet中心，该中心现已进入第四个年头，该中心与地区高中物理教师一起促进研究和教育项目，以及2)制作一部教育卡通片，通过赋予每个人难忘的动画个性，向学生传授各种类型的夸克和轻子。较小的外展项目包括参加大学开放参观活动和帮助小学生参加科学表演。该研究项目非常适合本科生、研究生和博士后的培养。通过拥有要分析的数据的项目、正在建设的项目和正在设计的项目，该小组可以在实验学科中为其学生提供全方位的培训。KU小组保持着通过互联网通过针对不同社区的网站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.
