The focus of the Penn State University particle physics group is three fold: completion and analysis activities of the ZEUS experiment at HERA at DESY; developmental work for the TOTEM experiment at the LHC at CERN; and participation in a Cosmic Ray muon study in collaboration with the ALICE experiment at CERN. The ZEUS experiment at DESY is a study of electron/positron-proton deep inelastic scattering (DIS) at a center-of-mass energy of 318 GeV to investigate the constituent structure of matter. Its primary aims are to study DIS at the highest exchanged photon virtualities, to probe electron and quark substructure down to distances of 10-18 cm, and to search for new families of excited leptons and quarks, in the 0.1-1 TeV mass range, indicative of physics beyond the Standard Model. During this next three-year grant period, HERA will provide high luminosity and lepton beam polarization. By mid 2007, the HERA-II program will cease operations, and the PSU group will transition to the TOTEM experiment at the LHC. For TOTEM, the group will conduct R&D on readout and trigger generation. TOTEM will investigate very forward particle production in high-energy proton-proton collisions. The goal of third (cosmic ray) project is to study high multiplicity muon bundles which might signify high-energy effects in primary cosmic ray interactions that are not included in current Monte Carlo programs that are simulating ultra high-energy cosmic rays. Broader impacts of the program, coordinated through Penn State University and the Pennsylvania Space Grant Consortium, include an annual series of summer Science Workshops for Educators, aimed at secondary school teachers.

宾夕法尼亚州立大学粒子物理小组的工作重点有三个方面：完成和分析DESY HERA的ZEUS实验; CERN LHC的TOTEM实验的开发工作;以及与CERN的ALICE实验合作参与宇宙射线μ子研究。 DESY的ZEUS实验是一项研究电子/正电子-质子深度非弹性散射（DIS）的实验，质心能量为318 GeV，以研究物质的组成结构。它的主要目标是在最高交换光子虚拟度下研究DIS，探测电子和夸克的子结构，直到10-18厘米的距离，并在0.1-1 TeV质量范围内寻找新的激发轻子和夸克家族，这表明物理学超越了标准模型。 在接下来的三年资助期内，HERA将提供高亮度和轻子束偏振。到2007年中期，HERA-II计划将停止运行，PSU小组将过渡到LHC的TOTEM实验。 对于TOTEM，该小组将进行读出和触发生成的研发。 TOTEM将研究高能质子-质子碰撞中非常前沿的粒子产生。 第三个（宇宙射线）项目的目标是研究高多重性μ介子束，这可能意味着初级宇宙射线相互作用中的高能效应，而这些效应不包括在目前模拟超高能宇宙射线的蒙特卡罗程序中。 该方案的更广泛影响是通过宾夕法尼亚州立大学和宾夕法尼亚空间赠款联合会协调的，包括针对中学教师的一系列年度教育工作者暑期科学讲习班。
