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.

该RUI提案要求继续支持对B介子衰变中CP破坏的研究计划和对标准模型（BSM）之外物理的研究。CP破坏被认为在重子生成和宇宙中观察到的物质-反物质不对称性中起着重要作用，但目前已知的标准模型中CP破坏的来源还不足以解释我们的物质主导宇宙。因此，在标准模型之外的物理学中必然会出现新的、更大的CP破坏源，这是非常合理的。B衰变是寻找这种效应的一个很好的方法，因为B工厂和Tevatron正在产生大量的数据，最终LHC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物理学的特定模型开发签名，特别是“小希格斯”模型。PI是印第安纳州中部一所本科大学的教授，他对中微子物理学中的弱相互作用以及B衰变有着长期的兴趣，这些学科非常适合作为粒子物理学前沿研究的入门。他非常积极地让本科生参与他的研究，事实上，他有一个令人印象深刻的记录，送学生到研究生院。他还与该领域的专家如A。彼得罗夫，韦恩州，和博士。索尼，布鲁克海文国家实验室.
