在QCD激发的相对论夸克模型框架下，基于准势方法计算了重轻介子基态、轨道和径向激发态的质量。轻夸克（q=u，d，s）和重夸克（Q=c，B）都被完全相对论地处理，而没有应用重夸克1/mQ展开。研究了（M2，J）和（M2，nr）平面上的Regge轨迹，得到了它们的参数。除了Ds 1（2460）和Ds 2（2460）态的质量外，计算结果与已有的实验数据符合得很好。
The masses of the ground, orbitally and radially excited states of heavy-light mesons are calculated within the framework of the QCD-motivated relativistic quark model based on the quasipotential approach. Both light (q=u,d,s) and heavy (Q=c,b) quarks are treated fully relativistically without application of the heavy-quark 1/mQexpansion. The Regge trajectories in the (M2,J) and (M2,nr) planes are investigated and their parameters are obtained. The results are in good agreement with available experimental data except for the masses of the anomalous,Ds1(2460) andstates.
