dc.descriptionIn this article, we study the vertices $D^*D^*P$, $D^*DV$ and DDV with the light-cone QCD sum rules. The strong coupling constants g_{D^*D^*P}, g_{D^*DP}, f_{D^*DV}, f_{D^*D^*V}, g_{DDV} and g_{D^*D^*V} play an important role in understanding the final-state interactions in the hadronic B decays. They relate to the basic parameters g, $λ$ and $β$ in the heavy quark effective Lagrangian respectively. Our numerical values of the g, $β$ and $λ$ are much smaller than most of the existing estimations. If the predictions from the light-cone QCD sum rules are robust, the final-state interaction effects maybe overestimated in the hadronic B decays.
