R. of IranJournal Article20141127Using QCD factorization for the hadronic matrix elements, we show that existing data, in<br />particular the branching ratios BR ( B →J/ψK) and BR ( B →J/ψπ), can be accounted for in this approach.<br />We analyze the decay B J /K( ) within the framework of QCD factorization. The calculation of the<br />relevant hard-scattering kernels for twist-2 and twist-3 is completed. We calculate this decay in a special scale<br />( mb ) and in two schemes for Wilson coefficients in NLO. We consider three functions for J / . The<br />twist-3 contribution involves the logarithmically divergent integral, we consider H 0 the canceling<br />divergent. The obtained results are in agreement with available experimental data.https://ijsts.shirazu.ac.ir/article_2179_382ae7c78eb8fff892e5ab88b10b2907.pdf
