Analysis of the vertices DDV and D^*DV with light-cone QCD sum rules

Author:: Zhi-Gang Wang
Journal:: The European Physical Journal C - Particles and Fields
Issue Date:: 2007
Abstract(summary):: In this article, we study the vertices DDV and D*DV with the light-cone QCD sum rules. The strong coupling constants g_DDV and f_D*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.
