The B → D(*)sπ decays in perturbative QCD
Zhi-Qing Zhang
Show affiliationsIn this paper, we calculate the branching ratios for B0 → D+sπ−, B+ → D+sπ0, B0 → D*+sπ− and B+ → D*+sπ0 decays in the perturbative QCD factorization approach. We find that the calculated branching ratios of these four decay channels agree well with the measured values and the current experimental upper limit. In the numerical calculation, we take the decay constant and the shape parameter of the vector meson D*s as 
MeV and 
respectively, which are larger than those in the previous calculations.
