重轻介子的一种相对论方程

A relativistic equation of heavy light meson

重味介子在强子谱研究中扮演着特殊的角色,它是含重夸克的最简单的强子体系.借助相对论性势夸克模型计算了各种D介子基态以及S波低激发态的能量,结果表明除了耦合道引起的质量移动外,赝标重味介子与矢量重味介子的质量分裂可归因于重轻夸克间的自旋耦合能.

Heavy flavour mesons play a special role in the study of hadron spectrum , w hich are the simplest hadronic system that contain heavy quarks . In this paper , T he energy spectrum of a variety of D mesons in their ground state and low‐lying excited S waves are calculated based on relativistic potential quark model .In addition to mass shift due to channel coupling ,the mass splitting between heavy flavored pesudoscalar mesons and vector mesons arise from spin‐spin interaction between quarks .
