This proposal requests continuing support for a program of research for the Huston.Bromberg group at Michigan State University (MSU) in experimental elementary particle physics based primarily on the CDF experiment and proposed NOvA experiment at the Fermilab Tevatron collider and the ATLAS experiment at the Large Hadron Collider (LHC) at CERN.For the past few decades, physicists have been able to describe with increasing detail the fundamental particles that make up the Universe and the interactions between them. Much of this success has been due to the Tevatron program at Fermilab with D0 and CDF making major contributions. This understanding is encapsulated in the Standard Model of particle physics, but it contains gaps and cannot tell us the whole story. To fill in the missing knowledge requires more and different experimental data, and the next big step to achieving this is with the LHC. This MSU group has made major contributions to the CDF experiment in its design, construction and operation of parts of the calorimeter and tracker and in the physics questions proposed as well as in many leadership roles. This group is now transitioning into the ATLAS program where it will parlay its wealth of experience in W/Z + jet final state(s) into a leadership role in such analyses. Such events serve as both a signal channel and background in Standard Model and Beyond the Standard Model physics. The group also has major responsibility in the design, installation and operation for parts of the calorimeter system including thee L1 trigger. This group works closely with phenomenologists with Huston serving as co-spokesman for the 24 member Coordinated Theoretical-Experimental Project on QCD (CTEQ) and one of the organizers of its workshops.Bromberg also is participating in the NOvA R&D program with his group having responsibility for quality assurance of the 13,000 km of WLS fiber. Finally, he has also joined the group testing a 250-liter LArTPC at Fermilab. On Broader Impacts, the group will continue its work primarily within the QuarkNet program as well as employing undergraduates in the research. Expansion of the Cosmic Ray Detector units into other schools is underway with the goal of coordinating time stamps between high schools to look for wide area cosmic ray showers. Science Days and permanent exhibits in an atrium setting at MSU related to the ATLAS program are planned.

该提案请求继续支持密歇根州立大学 (MSU) 的休斯顿·布罗姆伯格小组在实验基本粒子物理学方面的一项研究计划，该研究计划主要基于 CDF 实验，并提议在费米实验室 Tevatron 对撞机上进行 NOvA 实验，以及在欧洲核子研究中心 (CERN) 的大型强子对撞机 (LHC) 上进行 ATLAS 实验。在过去的几十年里，物理学家已经能够更详细地描述基本粒子 构成了宇宙以及它们之间的相互作用。这一成功很大程度上归功于费米实验室的 Tevatron 项目，其中 D0 和 CDF 做出了重大贡献。 这种理解被封装在粒子物理的标准模型中，但它存在缺陷，不能告诉我们整个故事。 填补缺失的知识需要更多不同的实验数据，而实现这一目标的下一个重要步骤是大型强子对撞机。 该密歇根州立大学小组在热量计和跟踪器部件的设计、构建和操作以及提出的物理问题以及许多领导角色方面为 CDF 实验做出了重大贡献。 该小组现在正在过渡到 ATLAS 计划，将利用其在 W/Z + 喷气机最终状态方面的丰富经验，在此类分析中发挥领导作用。 此类事件既是标准模型物理中的信号通道，也是标准模型物理之外的背景。 该小组还主要负责热量计系统部件（包括 L1 触发器）的设计、安装和操作。 该小组与现象学家密切合作，Huston 担任由 24 名成员组成的 QCD 理论实验协调项目 (CTEQ) 的联合发言人，也是其研讨会的组织者之一。Bromberg 还参与了 NOvA 研发计划，他的小组负责 13,000 公里 WLS 光纤的质量保证。 最后，他还加入了费米实验室 250 升 LArTPC 测试小组。在更广泛的影响方面，该小组将继续主要在 QuarkNet 项目内开展工作，并雇用本科生进行研究。 宇宙射线探测器装置正在扩展到其他学校，其目标是协调高中之间的时间戳，以寻找大范围的宇宙射线阵雨。 计划在密歇根州立大学中庭举办与 ATLAS 项目相关的科学日和永久性展览。
