Vertices of the $D_s^{(\ast )}{D}^{(\ast )}{K}^{\ast }$

Abstract

Taking into account the contributions of the quark-quark, quark-gluon, and gluon-gluon condensate corrections, the strong form factors and coupling constants of $D_{s0}^{\ast }{D}_0^{\ast }{K}^{\ast }$, $D_{s}D{K}^{\ast }$, $D_s^{\ast }{D}^{\ast }{K}^{\ast }$, $D_{s1}{D}_1{K}^{\ast }$, $D_s{D}^{\ast }{K}^{\ast }$, and $D_{s0}{D}_1{K}^{\ast }$ vertices are investigated within the three-point QCD sum rules method, without and with the $S{U}_f(3)$ symmetry.
