High Energy Physics Research with the DO Experiment

本提案要求支持堪萨斯大学高能物理组的研究项目，支持费米实验室的D0实验工作，以及康奈尔大学CESR正电子对撞机的CLEO实验工作。升级后的D0探测器刚刚开始在期待已久的费米实验室Tevatron质子-反质子对撞机Run II中采集世界能量前沿的数据。除了寻找最小标准模型之外的新现象，例如希格斯玻色子或已知粒子的超对称伙伴，D0实验将对顶夸克物理、W和Z物理、QCD和b夸克物理进行精确测量。堪萨斯小组在为D0升级建造硅跟踪器方面发挥了主导作用，还负责中央预淋浴器（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，以获得最大的检测效率。该小组在b夸克物理、硅和淋浴前探测器方面的专业知识都将用于标记含有b夸克的喷流。这是所有新的物理研究中至关重要的一步。堪萨斯小组还将继续分析CLEO数据，特别是在粲重子领域，它们传统上在这个领域发挥着重要作用。

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.
