Using QCD factorization for the hadronic matrix elements, we show that existing data, in
particular the branching ratios BR ( B →J/ψK) and BR ( B →J/ψπ), can be accounted for in this approach.
We analyze the decay B J /K( ) within the framework of QCD factorization. The calculation of the
relevant hard-scattering kernels for twist-2 and twist-3 is completed. We calculate this decay in a special scale
( mb ) and in two schemes for Wilson coefficients in NLO. We consider three functions for J / . The
twist-3 contribution involves the logarithmically divergent integral, we consider H 0 the canceling
divergent. The obtained results are in agreement with available experimental data.
