Within the framework of QCD factorization, various important corrections arising from higher twist distribution amplitudes of mesons in the hadronic B decays have been discussed. Since the energies of final state mesons M1, M2 are of the order of mB/2, the soft corrections between the two mesons will therefore decouple in order of AQCD/mb. Only hard interactions between (BM1) and M2 survive in the heavy b quark mass limit. The decays can be studied by means of the QCD factorization (QCDF) approach. |
