Abstract

We used QCD FACTORIZATION for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR (B-®J/yK) and BR (B-®J/yp), can be accounted for this approach. We analyzed the decay B®J /y K (p) within the framework of QCD FACTORIZATION. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale (m=mb) and in two schemes for Wilson coefficients in NLO. We considered three functions for J /y. The twist-3 contribution involves logarithmically divergent integral and also we considered pH=0 canceling divergent. The obtained results are in agreement with available experimental data.
