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.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。该奖项为乔治·梅森大学的基本粒子物理研究计划提供了支持。 PI Philip Rubin将通过CLEO-C合作完成他的魅力物理学研究，并加入在CERN（NA62）建造一种设备，以对Cabibbo-kobayashi-Maskawa（CKM）Quark Quark混合Matrix的KAONS的衰减速率与Pizer-Kaons to Pizer-Barino-Barino-nneutrino Mytrino进行测量，以对Cabibbo-Kobayashi-Maskawa（CKM）Quarko-barino Mote to pizo-nneutrino to pizo-kaon-nneutrino进行极为敏感的测量。中性和带电的通道都是干净的，但是标准模型和该模型以外的物理学的精确探针。特别是，对这些渠道速率的测量将为CP侵略提供深入的见解，CP违反，这是一种允许物质集中的对称性破坏，因此可以在宇宙中生命的发展。鲁宾和他的小组将在关键的益智否决系统上工作，有助于翻新NA48的强子量倍倍量训练仪，并提供监视和控制系统。过去，鲁宾几乎与本科生进行了研究。在继续致力于为研究中提供令人兴奋的本科经验的承诺时，他的部门的新博士学位。计划于2008年秋季开始，将使研究生成为高能量物理学计划的一部分。他的额外推广工作集中在学生发展和教师培训上，通过开发跨学科课程，同时设计旨在满足大学毕业和弗吉尼亚州认证要求。
