In this article, the three-point QCD sum rules are used to compute the strong coupling constants of vertices containing strange charmed mesons with the $K^{⁎}$. The coupling constants are calculated when both charm and $K^{⁎}$ states are off-shell. In this calculation, the contributions of the quark-quark, quark-gluon, and gluon-gluon condensates corrections are considered. Considering the $S{U}_f(3)$ symmetry, the coupling constant $D_0{K}^{⁎}{D}_{s0}^{⁎}$ and $D_1{K}^{⁎}{D}_{s0}^{⁎}$ vertices are calculated $7.25\pm 0.76$ and $9.69\pm 0.85{\text{ GeV}}^{-1}$, respectively.

标量和轴向矢量的介子的顶点与矢量kaon：三点QCD和规则

在本文中，三点QCD和规则用于计算包含奇有魅力介子的顶点的强耦合常数。 ${ķ}^{⁎}$。当魅力和${ķ}^{⁎}$状态是脱壳的。在此计算中，考虑了夸克-夸克，夸克-胶子和胶子-胶子冷凝物校正的贡献。考虑到$\mathrm{小号}{ü}_F（3）$ 对称，耦合常数 $d_0{ķ}^{⁎}{d}_{s0}^{⁎}$ 和 $d_{\mathrm{1个}}{ķ}^{⁎}{d}_{s0}^{⁎}$ 计算顶点 $7.25\pm 0.76$ 和 $9.69\pm 0.85{\text{ GeV}}^{-\mathrm{1个}}$， 分别。
