Abstract

Using QCD FACTORIZATION for the hadronic matrix elements, we show that existing data, in particular the branching ratios BR (`B ® J/YK) and BR (`B ® J/Yp), can be accounted for in this approach. We analyze the decay B ® J /YK (p) 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 (m=mb) and in two schemes for Wilson coefficients in NLO. We consider three functions for J/Y. The twist-3 contribution involves the logarithmically divergent integral, we consider rH=0 the canceling divergent. The obtained results are in agreement with available experimental data.
