Experimental High Energy Physics

本提案请求支持内布拉斯加大学对撞机物理研究项目。主要的焦点是费米实验室的D0实验。该小组在继续分析现有的Run I数据（收集于1992年至1996年）和2001年3月开始的Run II的D0升级中发挥主导作用，重点研究量子色动力学（QCD）的物理研究和寻找新粒子。最近的成就（也是一篇内布拉斯加州的博士论文）包括使用完整的Run I数据集搜索顶夸克的超对称伙伴。对于Run II，这个小组已经为新的2级介子触发器制造了电子设备。CMS实验目前正在瑞士日内瓦欧洲核子研究中心（CERN）的大型强子对撞机（LHC）的建设中，将是内布拉斯加大学小组的下一个主要实验。在CMS上，这个小组负责协调pp亮度的测量。在分析方面，该小组将通过专注于新粒子搜索和利用14 TeV大型强子对撞机的增强物理范围的QCD研究来扩展其在D0上的工作。最后，PI非常积极地参与本科和研究生教育项目，以及一些新颖的拓展项目，比如nsf单独资助的CROP项目。

This proposal requests support for the collider physics research program of the University of Nebraska. The primary focus is the D0 experiment at Fermilab. With leading roles in the continued analysis of existing Run I data (collected between 1992 and 1996) and in the D0 upgrade for Run II starting in March 2001, this group focuses on physics studies in Quantum Chromodynamics (QCD) and searches for new particles. Recent accomplishments (also a Nebraska PhD thesis) include a search for a supersymmetric partner to the top quark using the full Run I data set. For Run II, this group has built electronics for the new Level-2 muon trigger. The CMS experiment, currently under construction for the Large Hadron Collider (LHC) at the CERN laboratory in Geneva Switzerland, will be the next major experiment for the University of Nebraska group. On CMS, this group has the responsibility to coordinate the measurement of the pp luminosity. On analysis, this group will extend its work on D0 by concentrating on new particle searches and QCD studies exploiting the enhanced physics reach of the 14 TeV LHC. Lastly, the PI's are very heavily involved in undergraduate and graduate education projects as well as in novel outreach programs such as the separately-funded NSF-sponsored CROP program.
