Abstract

The strong coupling constants, $g_{D_{s} D K_{0}^{*}}$ , $g_{B_{s} B K_{0}^{*}}$ , $g_{D_{s}^{*} D K}$ , $g_{B_{s}^{*} B K}$ , $g_{D_{s}^{*} D K_{1}}$ and $g_{B_{s}^{*} B K_{1}}$ , where $K_{0}^{*}$ , $K$ and $K_{1}$ are scalar, pseudoscalar, and axial-vector kaon mesons, respectively, are calculated in the framework of three-point QCD sum rules. In particular, the correlation functions of the considered vertices when both $B (D)$ and $K_{0}^{*} (K) (K_{1})$ mesons are off shell are evaluated. In the case of $K_{1}$ , which is either $K_{1} (1270)$ or $K_{1} (1400)$ , the mixing between these two states are also taken into account. A comparison of the obtained result with the existing prediction on $g_{D_{s}^{*} D K}$ as the only coupling constant among the considered vertices, previously calculated in the literature, is also made.
