Decays of heavy vector mesons in the quark confinement model

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 ^*D andD ^*D branching ratios. It is found that the value ofM _c varies approximately in the interval 1.3 GeVM _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=">M _Q withE=M _H–M_Q=const for the decay amplitudes.
