This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award provides support for a new program of research in elementary particle physics at George Mason University. The PI, Philip Rubin, will complete his research in charm physics with the CLEO-c collaboration and join in constructing an apparatus at CERN (NA62) to make extremely sensitive measurements of elements of the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix by measuring the decay rate of kaons to pizero-neutrino-neutrino-bar beginning with the charged kaon mode. Both the neutral and charged channels are clean but exacting probes of the Standard Model and of physics beyond this model. In particular, measurements of the rates of these channels will provide great insight into CP-violation, a symmetry breaking that permits the concentration of matter, and therefore the development of life, in the universe. Rubin and his group will work on the critical muon veto system, helping to refurbish NA48's hadron calorimeter and providing the monitoring and controls system. In the past, Rubin has conducted his research almost exclusively with undergraduate students. While continuing his commitment to providing exciting undergraduate experiences in research, his Department's new Ph.D. program, which commenced in Fall 2008, will allow for graduate students to be part of the high energy physics program. His additional outreach efforts are focused on student development and teacher training by developing interdisciplinary courses designed simultaneously to meet University graduation and Virginia state certification requirements.

该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。该奖项为乔治梅森大学基本粒子物理学的新研究项目提供支持。 PI Philip Rubin 将与 CLEO-c 合作完成粲物理方面的研究，并参与在 CERN (NA62) 建造一个装置，通过从带电 kaon 模式开始测量 kaons 到 pizero-neutrino-neutrino-bar 的衰变率，对 Cabibbo-Kobayashi-Maskawa (CKM) 夸克混合矩阵的元素进行极其灵敏的测量。中性通道和带电通道都是标准模型和超出该模型的物理的干净但严格的探针。特别是，对这些通道速率的测量将提供对CP破缺的深入了解，CP破缺是一种对称性破缺，它允许物质集中，从而促进宇宙中生命的发展。 Rubin 和他的团队将致力于关键的 μ 介子否决系统的研究，帮助翻新 NA48 的强子热量计并提供监测和控制系统。过去，鲁宾几乎只针对本科生进行研究。在继续致力于提供令人兴奋的本科生研究经验的同时，他的部门的新博士学位。该项目于 2008 年秋季开始，将允许研究生参加高能物理项目。他的额外外展工作侧重于学生发展和教师培训，开发同时设计的跨学科课程，以满足大学毕业和弗吉尼亚州认证要求。
