摘要：
In this article, we study the vertices DDV and D*DV with the light-cone QCD sum rules. The strong coupling constants gDDV and fD*DV play an important role in understanding the final-state re-scattering effects in the hadronic B decays. They are related to the basic parameters β and λ respectively in the heavy quark effective Lagrangian; our numerical values are smaller than the existing estimations.
