This proposal is for the frontier collider-physics research program of the Experimental High Energy Physics group at the University of Nebraska, Lincoln (UNL). The D-Zero collider experiment at the Fermi National Accelerator Laboratory near Chicago is the primary focus of this research with a future program involving the CMS experiment at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. Recently, the PIs have brought three graduate students through their PhDs and physics publication processes; guided several other publications of D-Zero Run I data; met the Level-3 specifications for triggering with a full suite of physics object tools and strategy for maximizing efficiency; and completed an electronics contribution to the upgrade Level-2 muon system for the experiment. The PIs have continuing and new responsibilities for physics analysis initiatives in the higher energy, higher-luminosity Run II. These have been new particle searches and studies of QCD processes. In addition, they propose to build on their long experience in D-Zero and draw on a Run II data set at least 20 times the size of its Run I data set to pursue unprecedented studies in QCD, new particle searches, and W/Z boson production. The physics pursuits of the group are coupled with leadership responsibilities in the triggering, monitoring, luminosity measurement, and operation of the experiment. The CMS Experiment is a natural extension their work as the CERN LHC opens a new energy frontier in 2008. The UNL group has responsibility for coordinating and implementing the measurement of the proton-proton luminosity in CMS and for the physics trigger simulation studies of certain forward physics processes. The group proposes to escalate their preparations for studies at the next energy frontier. The combination of these projects will continue to provide the group with research and education opportunities at the forefront of the field. Through the NSF-funded outreach project CROP (Cosmic Ray Observatory Project), The PIs have established themselves as specialists in education and outreach. In the first 4 years of this expanding project, the UNL group has established a network of 21 instrumented high-school cosmic-ray research stations that will soon be studying extensive air showers in Nebraska simultaneously. CROP is serving as a model for similar emerging high-school cosmic-ray efforts in the U.S., Canada, and abroad. Outgrowths of CROP are contributions of the PIs to education efforts in the cosmic ray Auger Southern Observatory and HEP outreach initiatives and national committees, in which a small investment of time carries a large impact.

这是内布拉斯加大学林肯分校实验高能物理组的前沿对撞机物理研究计划。在芝加哥附近的费米国家加速器实验室的D-零对撞机实验是这项研究的主要重点，未来的计划涉及在瑞士日内瓦欧洲核子研究中心的大型强子对撞机（LHC）的CMS实验。最近，PI带来了三名研究生通过他们的博士学位和物理出版过程;指导了其他几个D-Zero Run I数据的出版物;满足了3级触发的规范，使用了一整套物理对象工具和策略来最大限度地提高效率;并完成了对升级2级μ子系统的电子贡献。PI在更高能量，更高亮度的运行II中继续承担物理分析计划的新责任。这些都是新的粒子搜索和QCD过程的研究。此外，他们还建议利用他们在D-Zero方面的长期经验，利用至少是其Run I数据集20倍的Run II数据集，在QCD、新粒子搜索和W/Z玻色子生产方面进行前所未有的研究。该小组的物理追求与触发，监测，光度测量和实验操作的领导责任相结合。CMS实验是他们工作的自然延伸，因为CERN LHC在2008年开辟了一个新的能源前沿。UNL小组负责协调和实施CMS中质子-质子光度的测量，并负责某些前向物理过程的物理触发模拟研究。该小组建议加强他们对下一个能源前沿研究的准备。这些项目的结合将继续为该集团提供该领域最前沿的研究和教育机会。通过国家科学基金会资助的外展项目CROP（宇宙射线观测项目），PI已经成为教育和外展方面的专家。在这个不断扩大的项目的前4年，UNL小组已经建立了一个由21个装有仪器的高中宇宙射线研究站组成的网络，这些研究站很快将同时研究内布拉斯加州的大范围空气簇射。CROP正在成为美国类似的新兴高中宇宙射线研究的典范，加拿大和国外。太平洋区域组织理事会的成果是主要研究员对宇宙射线俄歇南方天文台和高等教育方案外联举措和国家委员会的教育工作的贡献，在这些方面，投入少量时间就会产生巨大影响。
