Experimental High Energy Physics Research at the D-Zero and CMS Collider Experiments

本提案请求支持伊利诺伊大学芝加哥分校实验高能物理组的研究项目。该小组自1990年以来一直是D0合作的成员，自1995年以来一直是CMS合作的成员。在费米实验室Tevatron对撞机的D0实验中，该小组将集中精力进行Run II物理分析，2级触发系统，以及可能的探测器升级，以便在LHC启动之前实现至少20反飞巴的综合光度。在目前正在瑞士日内瓦欧洲核子研究中心（CERN）实验室为大型强子对撞机（LHC）建造的CMS探测器上，该小组打算扩大其对强子量热计的参与，并开始在硅跟踪器上进行新的努力。CMS预计将在大型强子对撞机启动时成为该小组的主要焦点，目前预计在2006年启动。对于D0探测器，该小组正在开发2级触发量热计，它将识别电子和喷流，并计算缺失的横向能量。该小组将继续负责操作、维护和改进量热计二级触发系统。该小组将参与考虑各种探测器升级方案，重点研究与硅跟踪器和触发系统相关的研究。该小组的研究重点是在尽可能高的能量下继续研究高pT物理。之前的分析经验和技术职责使这个小组处于一个独特的位置，可以在寻找长期寻找的希格斯玻色子的Tevatron中发挥主导作用。该小组设计并制造了CMS强子量热计光学读出系统的一部分，最近还承担了该系统的1级读出和控制处理器的开发工作。随着Gerber的加入，CMS探测器的参与将会扩大，因为该小组将成为负责CMS外部硅跟踪器的五所美国大学之一。UIC物理系在本科生、研究生和博士后的教育和研究培训方面有着悠久的历史，并向社区提供服务。这些努力将继续并扩大。

This proposal requests support for the research program of the experimental high-energy physics group of the University of Illinois Chicago. This group has been a member of the D0 collaboration since 1990 and of the CMS collaboration since 1995. On the D0 experiment at the Fermilab Tevatron collider, the group will concentrate on Run II physics analysis, the Level-2 trigger system, and on possible detector upgrades needed to achieve an integrated luminosity of at least 20 inverse femtobarns before LHC turn-on. On the CMS detector, currently under construction for the LHC collider at the CERN laboratory in Geneva Switzerland, this group intends to expand its involvement in the hadron calorimeter and start a new effort on the silicon tracker. CMS is expected to become the group's main focus by the time the LHC turns on, currently expected in 2006. For the D0 detector, this group is developing the calorimeter Level-2 trigger that will identify electrons and jets, and calculated missing transverse energy. The group will remain responsible for operating, maintaining and improving the calorimeter Level-2 trigger system. The group will participate in considering various detector upgrade scenarios concentrating on studies related to the silicon tracker and the trigger system. The research focus of the group is to continue study of high pT physics at the highest energy possible. Previous analysis experience and technical responsibilities put this group in a unique position to take a leading role in the search for the long-sought Higgs boson at the Tevatron. This group has designed and fabricated part of the optical readout system for the CMS hadron calorimeter and has recently accepted responsibility for development of the Level-1 readout and control processors for the same system. With the addition of Gerber to the faculty, involvement in the CMS detector will expand, as the group becomes one of five US universities responsible for the outer silicon tracker of CMS. The UIC Department of Physics has a long history in education and research training of undergraduates, graduate students and post-docs, as well as outreach to the community. These efforts will be continued and expanded.
