The BABAR experiment at Stanford Linear Accelerator Center is collecting data with several hundred millions of B mesons already produced. It is one of the two dedicated "B-factories" (the other one is the BELLE experiment in KEK in Japan), which are the best-suited experiments for B-physics. After the early goal to discover violation of matter- antimatter symmetry, the BABAR experiment is now set to search for physics beyond the Standard Model via rare decays. Here is proposed a program of B physics in the BABAR experiment that targets this topic.The CMS experiment at LHC, now completing construction, will allow the direct exploration of new effects at the highest energy scale of accelerators. The primary focus if this group in to investigate B meson production as well as additional decay modes available at the CMS experiment. Thus the PI will exploit the existing potential of B-physics with the BABAR experiment, and build on this experience to start the physics studies on CMS.

斯坦福直线加速器中心的BABAR实验正在收集已经产生的数亿个B介子的数据。它是两个专门的“b工厂”之一（另一个是日本KEK的BELLE实验），这是最适合b物理的实验。在早期的目标是发现物质-反物质对称的破坏之后，BABAR实验现在被设定为通过罕见的衰变来寻找超越标准模型的物理。本文针对本课题提出了BABAR实验中B物理的方案。大型强子对撞机的CMS实验，目前正在完成建设，将允许在加速器的最高能量尺度上直接探索新的效应。该小组的主要工作重点是研究B介子的产生以及CMS实验中可用的其他衰变模式。因此，PI将通过BABAR实验挖掘b物理的现有潜力，并在此经验的基础上启动CMS的物理研究。
