We use the QCD sum rules for the three-point correlation functions to compute the strong coupling constants of the meson vertices $J/\psi D_{s}^{*} D_{s}^{*}$. 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 $g_{J/\psi D^{*}_{s} D^{*}_{s}} = 7.47^{+1.04}_{-0.71}.$.

J/ψDs∗Ds∗$J/\psi D_{s}^{*} D_{s}^{*}$ 形状因子和强耦合常数的 QCD 总和规则计算

我们使用三点相关函数的 QCD 求和规则来计算介子顶点 $J/\psi D_{s}^{*} D_{s}^{*}$ 的强耦合常数。使用 QCD 求和规则，我们获得顶点的形状因子、耦合常数和截止参数。包括不确定性。耦合常数获得的结果为 $g_{J/\psi D^{*}_{s} D^{*}_{s}} = 7.47^{+1.04}_{-0.71}.$。
