Abstract(summary):

We use the QCD sum rules for the three-point correlation functions to compute the strong coupling constants of the meson vertices JI*Ds*Ds*. Using the QCD sum rules, we obtain the form factor of the vertex, the coupling constant, and the cut off parameter. Uncertainties are included. The results obtained for the coupling constants are,g.u*D;, =3D 7.47+01:7041
