Description
The strong coupling constants, $g_{B^{\ast}_{s}BK}$, $g_{D^{\ast}_{s}D K}$, where $K_1$ is pseudoscalar kaon meson, 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 $K$ mesons are off-shell are evaluated. A comparison of the obtained result with the existing prediction on $g_{D^{\ast}_{s}D K}$ as the only coupling constant among the considered vertices, previously calculated in the literature, is also made.
