Abstract

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/m _Q expansion. The Regge trajectories in the (M ²,J) and (M ²,n _r) 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
