This proposal requests support for the research program of the high energy physics group at the University of Kansas, for work on the D0 experiment at Fermilab and also for work on the CLEO experiment at the Cornell University CESR electron-positron collider. The upgraded D0 detector has just begun taking data at the world's energy frontier in the long-anticipated Run II at the Fermilab Tevatron proton-antiproton collider. In addition to searches for new phenomena beyond the minimal Standard Model, e.g., for the Higgs boson or for supersymmetric partners to the known particles, the D0 experiment will make precision measurements in top-quark physics, W and Z physics, QCD, and b-quark physics. The Kansas group has played a leading role in building the silicon tracker for the D0 upgrade and is also responsible for the offline software support of the central preshower (CPS) detector. This group will also align, calibrate, and fine-tune the CPS detector for maximal detection efficiency. The group's expertise in b-quark physics, silicon, and preshower detectors will all be put to use in tagging jets containing a b-quark. This is a crucial step in all new physics searches. The Kansas group will also continue its analysis of CLEO data, especially in the area of charmed baryons, where they have traditionally played an important role.

该提案要求支持堪萨斯大学高能物理组的研究计划、费米实验室的D 0实验工作以及康奈尔大学CESR正负电子对撞机的CLEO实验工作。 升级后的D 0探测器刚刚开始在费米实验室Tevatron质子-反质子对撞机的期待已久的运行II中获取世界能源前沿的数据。 除了寻找最小标准模型之外的新现象，例如，对于希格斯玻色子或已知粒子的超对称伙伴，D 0实验将在顶夸克物理学、W和Z物理学、QCD和b夸克物理学中进行精确测量。堪萨斯集团在为D 0升级构建硅跟踪器方面发挥了主导作用，同时还负责中央预播（CPS）探测器的离线软件支持。 该小组还将对准、校准和微调CPS探测器，以实现最大的探测效率。 该小组在b夸克物理学、硅和预散射探测器方面的专业知识都将用于标记含有b夸克的喷流。 这是所有新物理学研究的关键一步。 堪萨斯小组还将继续分析CLEO数据，特别是在它们传统上发挥重要作用的魅力重子领域。
