In this paper, the strong form factors and coupling constants of D_sDK^* and D_sD^*K^* vertices are investigated within the three-point QCD sum rules method with and without the SU_f(3) symmetry. In this calculation, the contributions of the quark-quark, quark-gluon, and gluon-gluon condensate corrections are considered. As an example of specific application of these coupling constants, the branching ratio of the hadronic decay B^+→K^*^0 π^+ is analyzed based on the one-particle-exchange which

... s one of the phenomenological models. In this model, B decays into a D_s D^* intermediate state, and then these two particles exchange a D (D^*) producing the final K^* and π mesons. In order to compute the effect of these interactions, the D_s D K^* and D_s D^* K^* form factors are needed.
