Particle Physics at High Energy Colliders

该提案要求继续支持休斯顿的研究项目。密歇根州立大学（MSU）的Bromberg小组的基本粒子物理实验主要基于CDF实验和在费米实验室Tevatron对撞机上的NOvA实验和在欧洲核子研究中心（CERN）的大型强子对撞机（LHC）上的ATLAS实验。在过去的几十年里，物理学家已经能够越来越详细地描述构成宇宙的基本粒子以及它们之间的相互作用。这一成功很大程度上要归功于费米实验室的Tevatron项目，D0和CDF做出了重大贡献。这种理解被封装在粒子物理学的标准模型中，但它包含了空白，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使用大型强子对撞机。这个密歇根州立大学的小组在CDF实验的设计、建造和操作部分量热计和跟踪器以及提出的物理问题以及许多领导角色方面做出了重大贡献。该小组现在正在过渡到ATLAS项目，在那里它将发挥其在W/Z +喷气机最终状态方面的丰富经验，在这种分析中发挥领导作用。这些事件在标准模型和超越标准模型物理学中既是信号通道又是背景。该小组还主要负责热量计系统部分的设计、安装和操作，包括三个L1触发器。这个小组与现象学家密切合作，休斯顿是由24名成员组成的QCD协调理论实验项目（CTEQ）的联合发言人，也是该项目研讨会的组织者之一。Bromberg还参与了NOvA研发项目，他的团队负责13000公里WLS光纤的质量保证。最后，他还加入了在费米实验室测试250升LArTPC的小组。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，并雇用本科生参与研究。宇宙射线探测器正在向其他学校扩展，其目标是协调高中之间的时间戳，以寻找广域宇宙射线阵雨。计划在密歇根州立大学的中庭设置科学日和与ATLAS项目相关的永久性展览。

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.
