Findings

Calculated strong form factors for various vertices.

Determined coupling constants with and without $SU_{f}(3)$ symmetry.

Enhanced understanding of meson interaction dynamics.

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 $D^*_{s0}D^*_0K^*$, $D_sDK^*$, $D^*_sD^*K^*$, $D_{s1}D_1K^*$, $D_sD^*K^*$, and $D_{s0}D_1K^*$ vertices are investigated within the three-point QCD sum rules method, without and with the $SU_{f}(3)$ symmetry.
