CP Violation and Rare-Decay Studies

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项为乔治梅森大学基本粒子物理学研究的新计划提供支持。PI Philip Rubin将与CLEO-c合作完成他在魅力物理学方面的研究，并加入CERN（NA 62）的设备，通过测量从带电K介子模式开始的K介子到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越标准模型的物理学的干净而精确的探针。特别是，测量这些通道的速率将提供对CP破坏的深入了解，CP破坏是一种对称性破缺，允许宇宙中物质的集中，从而允许生命的发展。鲁宾和他的团队将致力于关键μ子否决系统，帮助更新NA 48的强子量能器，并提供监测和控制系统。在过去，鲁宾几乎只对本科生进行研究。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。该计划于2008年秋季开始，将允许研究生成为高能物理计划的一部分。他的额外推广工作的重点是学生发展和教师培训，开发跨学科课程，同时设计，以满足大学毕业和弗吉尼亚州的认证要求。

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.
