Heavy-light meson spectroscopy and Regge trajectories in the relativistic quark model

AbstractThe 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/mQ expansion. 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 n

Relativistic treatment of the decay constants of light and heavy mesons

Semileptonic and nonleptonic decays of the B_c meson to charmonium and D mesons are studied in the framework of the relativistic quark model. The decay form factors are explicitly expressed through the overlap integrals of the meson wave functions in the whole accessible kinematical range. The relativistic meson wave functions are used for the calculation of the decay rates. The obtained results are compared with the predictions of other approaches.
