摘要
手征夸克模型是具有QCD基本精神的唯象模型,而手征SU(3)夸克模型和扩展的手征SU(3)夸克模型在研究轻夸克系统时已经取得了不小的成功.本文将这两个模型进一步推广到含重味夸克的体系,利用含重味介子D、D*、Ds、Ds*、B、B*、Bs、Bs*的实验数据重新系统地拟合重味夸克相关的模型参数,并分析单胶子交换势和禁闭势的变化趋势.
The chiral quark model is a phenomenological model with QCD spirits, and the chiral SU(3) quark model and the extended chiral SU(3) quark model have already obtained great successes in studying the light quark systems. These two models are extended to the states including heavy quarks. Model parameters for heavy quarks are systematically calculated by fitting experimental masses of the heavy mesons D,D^* ,Ds ,Ds^* ,B,B^* ,Bs and Bs^*. The single gluon exchange potentials and the confinement potentials are also analysed.
