Decays of heavy vector mesons in the quark confinement model

Abstract

We analyze the radiative and hadronic decays of vector heavy mesons within the relativistic quark model with confined light quarks. The only adjustable parameters in this approach are the values of constituent masses of heavy quarks (M c andM b). We adjust them using the available experimental data from CLEO and ARGUS-collaborations for theD *→Dγ andD *→Dπ branching ratios. It is found that the value ofM c varies approximately in the interval 1.3 GeV<M c<1.65 GeV. We give the predictions for the absolute values of decay widths and compare our results with those obtained in other approaches. Also we consider the heavy quark limitM Q→∞ withE=M H−MQ=const for the decay amplitudes.
