RUI: Theoretical Investigation of CP Violation in Extensions of the Standard Model

RUI的这项提议要求继续支持B介子衰变中CP破坏的研究计划，以及寻找超越标准模型(BSM)的物理。CP破坏被认为在宇宙中的重生和观测到的物质-反物质不对称中起着重要作用，但目前标准模型中已知的CP破坏源不够大，不足以解释我们以物质为主的宇宙。因此，新的、更大的CP破坏源一定会出现在标准模型之外的物理学中，这是很有可能的。B衰变是寻找这种效应的绝佳方法，因为B工厂和泰瓦顿正在产生海量数据，最终大型强子对撞机也会这样做。此外，B介子的二体和三体衰变提供了许多可能违反CP的关联。PI将为BSM物理的特定模型开发签名，特别是“小希格斯”模型。派是印第安纳州中部一所本科大学的教授，他对中微子物理和B衰变的弱相互作用有着长期的兴趣，这两个学科非常适合作为粒子物理前沿研究的入门课程。他非常积极地让本科生参与他的研究，事实上，他在送学生去研究生院方面有着令人印象深刻的记录。他还与该领域的专家积极合作，如韦恩州立大学的A.Petrov教授和布鲁克海文国家实验室的A.Soni博士。

This RUI proposal requests continued support for a program of research on CP violation in B-Meson decays and the search for physics beyond the standard model (BSM). CP violation is believed to play an important role in baryogenesis and the observed matter-anti-matter asymmetry in the universe, but the currently known source of CP violation in the standard model is not large enough to account for our matter-dominated universe. Thus it is very plausible that new and much larger sources of CP violation must occur in physics beyond the standard model. B-decays are an excellent play to search for such effects because B-factories and the Tevatron are producing vast amounts of data, and eventually LHC will do likewise. In addition, the two- and three-body decays of B-mesons provide numerous correlations which may violate CP. The PI will develop signatures for particular models of BSM physics, especially the "little Higgs" models. The PI, a professor at an undergraduate university in central Indiana, has a long term interest in weak interations in neutrino physics as well as B-decays,subjects which are well suited as introductions to research at the frontiers of particle physics. He is very active in involving undergraduates in his research and, in fact, he has an impressive record of sending students to graduate school. He also has an active collaborations with experts in the field such as Prof. A. Petrov, Wayne State, and Dr. A. Soni, Brookhaven National Laboratory.
