摘要
Some of the nonleptonic decays of B mesons are calculated by applying the model-independent QCD sum rule results of the universal form factors in heavy quark symmetry and the factorization hypothesis. The decay constant of the D(s) meson is extracted to be f(Ds) = (281+/-56) MeV. A test of the factorization hypothesis and some ratios of the branching fractions are discussed.
