  1. 本文利用重层子模型中得到的介子B-S波函数讨论介子的轻子型弱衰变、电磁衰变和各种二体强衰变过程。

    Using the B-S wave functions of mesons in the massive straton model , we discuss their weak decay , electromagnetic decay , and particularly hadronic decay processes .

  4. 在论文的综述部分(前三章),我们首先对粒子物理的标准模型以及B介子弱衰变的理论框架进行了简单的介绍,并给出了标准模型下威尔逊系数的表达式;

    In the first three chapters , we made a review for the theoretical framework of Standard Model and B physics . We presented the extraction of Wilson coefficients ;

  5. D和Ds非轻子弱衰变的分支比与实验值不符。

    For D and Ds mesons , the nonleptonic decay branching ratios do not respect data .
