Abstract：
Hadronic model wavefunctions are applied to calculate hadronic matrix elements of decays of D,B mesons in the Baner-Stech-Wirbel(BSW) approach we have analyzed several different models of valence Pock state wavefunctions, studied their properties and calculated branch ratios of exclusive decays of D, B mesons. The resultsshow that predictions of the different wavefunction models can fit most of the present data within the errors by choosing reasonable a₁,a₂. Therefore, it will be helpful for studying the model dependence and the reliability of the BSW approach from further theoretical investigation on factorization of weak processes and on the hadronic wavefunctions and from the further precisely experimental measurements.
