The D0 Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the world's premier high-energy accelerator, the Tevatron Collider, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe.CMS (Compact Muon Solenoid) is a general purpose detector designed to run at the highest luminosity at the LHC. The CMS detector has been optimized for the search of the SM Higgs boson over a mass range from 90 GeV to 1 TeV, but it also allows detection of a wide range of possible signatures from alternative electro-weak symmetry breaking mechanisms. CMS is also well adapted for the study of top, beauty and tau physics at lower luminosities and will cover several important aspects of the heavy ion physics program. The program of this group at the University of Illinois at Chicago (UIC) is centered on the D0 experiment currently running at the Fermilab Tevatron proton-antiproton collider, and is evolving to the CMS experiment that is scheduled to start operations in 2007 at the proton-proton Large Hadron Collider (LHC) at CERN in Geneva, Switzerland.The broader impacts of the proposed activities are multiple and diverse. The technological advances of high energy frontier experiments help all sciences and engineering. The challenges that must be overcome to build and commission complicated trigger and silicon systems enhance the disciplinary knowledge in the relevant engineering fields. The physics analyses and hardware projects, that UIC HEP students and postdocs are engaged in, allow them to gain valuable experience and knowledge and pursue successful careers in the academia or private sector. Besides the general benefits of experimental HEP research to society, this group is engaged in active outreach efforts through QuarkNet and a collection of cosmic ray detectors located around the city of Chicago. They also serve and train a large urban population with a significant component of underrepresented minorities in Chicago High Schools.

D 0实验是一个由世界范围内的科学家合作进行的关于物质基本性质的研究。该实验位于美国伊利诺伊州巴达维亚的费米国家加速器实验室（Fermilab）的世界顶级高能加速器Tevatron对撞机上。研究重点是在最高可用能量下精确研究质子和反质子的相互作用。CMS（Compact Muon Solenoid）是一种通用探测器，设计用于在LHC的最高光度下运行。CMS探测器已被优化，用于在90 GeV至1 TeV的质量范围内搜索SM希格斯玻色子，但它也允许检测来自替代电弱对称性破缺机制的各种可能的签名。CMS也非常适合于在较低光度下研究顶部，美丽和tau物理，并将涵盖重离子物理计划的几个重要方面。该小组在芝加哥的伊利诺伊大学（UIC）的计划是以目前在费米实验室Tevatron质子-反质子对撞机上运行的D 0实验为中心，并正在发展到CMS实验，该实验计划于2007年在瑞士日内瓦的欧洲核子研究中心的质子-质子大型强子对撞机（LHC）上开始运行。高能前沿实验的技术进步有助于所有科学和工程。构建和调试复杂的触发器和硅系统必须克服的挑战增强了相关工程领域的学科知识。UIC HEP学生和博士后从事的物理分析和硬件项目使他们能够获得宝贵的经验和知识，并在学术界或私营部门追求成功的职业生涯。除了实验性HEP研究对社会的一般好处外，该小组还通过QuarkNet和位于芝加哥周围的宇宙射线探测器集合积极开展外展工作。他们还服务和培训了大量的城市人口，其中芝加哥高中的少数民族人数不足。
