Research in Hadron Collider Physics

该提案要求支持圣母大学小组的研究计划，该计划强调在强子对撞机上进行的实验。关键的物理领域包括顶夸克的研究，对标准模型的持续测试，对标准模型之外的物理的探索，以及对希格斯扇区的调查。该计划的一个重要方面是下一代高能实验物理学家的教育和准备。该项目以费米实验室的D0实验和瑞士日内瓦欧洲核子研究中心（CERN）实验室正在建设的大型强子对撞机（LHC）的CMS实验为中心。D0实验的物理涉及顶夸克、强相互作用物理（QCD）、电弱物理（W/Z）、b夸克物理的研究，并寻找新的现象。特别令人感兴趣的是发现质量小于180 GeV/c2的希格斯玻色子的可能性。大型强子对撞机的实验将扩展物理学的视界，包括希格斯扇区和超对称的完全覆盖。巴黎圣母院项目包括四个主要方面：(a) Fermilab Run II D0探测器的安装、调试和校准；(b)对Run II数据的分析，重点是ND教师和研究生挑选的主题，例如BS混合，超对称的搜索，硬衍射，顶夸克的研究，额外维度证据的搜索和希格斯搜索；(c)全面协调和开发新的D0闪烁光纤跟踪器的跟踪算法和软件，包括跟踪算法、探测器模拟、校准、模式识别和跟踪拟合；(d)在大型强子对撞机上研发和建造CMS探测器。在CMS方面，本课组参与强子量热计（HCAL）的研制、建设和实施，重点是探测器分系统的光电读出。该小组还在涉及全国高中教师和学生的高能物理Quarknet项目的发展中发挥了主要领导作用。

This proposal requests support for the research program of the Notre Dame group, which emphasizes experiments performed at hadron colliders. Key physics areas include the study of the top quark, the continued testing of the Standard Model, the search for physics beyond the Standard Model, and the investigation of the Higgs sector. An important facet of this program is the education and preparation of the next generation of experimental high-energy physicists. This program is centered on the D0 experiment at Fermilab and the CMS experiment currently under construction at the Large Hadron Collider (LHC) at the CERN laboratory in Geneva Switzerland. The physics of the D0 experiment involves the study of the top quark, strong interaction physics (QCD), electroweak physics (W/Z), B-quark physics, and searches for new phenomena. Of particular interest is the possibility of discovering a Higgs boson with a mass less than 180 GeV/c2. The LHC experiment will expand the physics horizon to include complete coverage of the Higgs sector and supersymmetry.The Notre Dame program involves four major aspects: (a) installation, commissioning and calibration of the D0 detector for Run II at Fermilab; (b) analysis of the Run II data with emphasis on topics singled out by the ND faculty and graduate students, e.g., BS mixing, search for supersymmetry, hard diffraction, study of the top quark, searches for evidence of extra dimensions, and Higgs searches; (c) overall coordination and development of tracking algorithms and software for the new D0 scintillating fiber tracker including track algorithms, detector simulation, calibration, pattern recognition, and track fitting; and (d) detector R&D and construction of the CMS detector at the LHC.On CMS, this group is participating in the development, construction and implementation of the hadron calorimeter (HCAL) with emphasis on the electro-optical readout of the detector sub-system. This group has also provided major leadership in development of the Quarknet project involving high school teachers and students in high-energy physics nationwide.
