Heavy Quark Physics at BaBar

该提案要求支持辛辛那提大学的一个小组，以斯坦福大学线性加速器中心（SLAC）的BaBar实验为基础，开展实验基本粒子物理学的研究和教育计划。BaBar的主要目的是研究中性B介子（B 0 s）及其反粒子衰变中粒子-反粒子不对称性（CP破坏）的起源。基本粒子相互作用的标准模型预言了这种CP不对称性。BaBar实验的目的是检测许多B衰变模式，从而研究CP破坏的时间依赖性。除了分析贡献，该小组还参与了DIRC（内反射切伦科夫辐射探测器）的操作和软件开发。

This proposal requests support for a group at the University of Cincinnati for a program of research and education in experimental elementary particle physics based on the BaBar experiment at the Stanford Linear Accelerator Center (SLAC). They are also completing the analysis of a hadronic charm production experiment E791 at Fermilab.The main aim of BaBar is to study the origin of particle-antiparticle asymmetry (CP violation) as seen in the decays of neutral B mesons (B0s) and their antiparticles. The Standard Model of elementary particle interactions predicts such CP asymmetries. The BaBar experiment is designed to detect many of the B decay modes and thus to study the time-dependence of CP violation. In addition to the analysis contributions, the group is also involved with the operations and software development of the DIRC (Detector of Internally Reflected Cherenkov radiation).
