This proposal requests funds to support experimental studies of heavy quark physics with the BaBar Collaboration at the Stanford Linear Accelerator Center (SLAC). This research program in experimental particle physics centers on a primary physics goal of elucidating the source of CP violation (matter-anti-matter asymmetry) through the study of the decay of mesons containing the bottom quark. A secondary physics goal is to probe aspects of the strong interaction force by making precise studies of baryons containing the charm quark of hadronic decays of the B-meson. Such studies are challenging both theoretically, since they are difficult to calculate from first principles using the standard theory (Quantum ChromoDynamics or QCD); and experimentally, since they occur with very small probability. The Stanford group will also conduct an R&D program on chemical vapor deposition (CVD) diamond sensors for use in radiation monitoring and single-particle detection in high-radiation environments. This program will be carried out with the BaBar detector and the PEP-II storage ring as well as other facilities at SLAC.

该提案要求资金通过斯坦福线性加速器中心（SLAC）的巴巴尔合作来支持重型夸克物理学的实验研究。实验粒子物理学的该研究计划以阐明CP违规来源的主要物理目标（Matter-Arti-Mattermememetry）的基础，该目标通过研究含有底部夸克的介子的衰变。次要物理目标是通过对包含B-Meson Hadronic腐烂魅力的重子进行精确研究来探测强相互作用的方面。从理论上讲，这种研究都在挑战，因为它们很难使用标准理论（量子染色体动力学或QCD）来计算第一原理。并且在实验上，因为它们发生的概率很小。斯坦福大学还将在高辐射环境中进行用于辐射监测和单粒子检测的化学蒸气沉积（CVD）钻石传感器的研发计划。该程序将使用Babar探测器和PEP-II存储环以及SLAC的其他设施进行。
