In the framework of QCD factorization, we study the B meson exclusive decays B → χcJK where the spin-triplet P-wave charmonium states χcJ(J = 0, 1, 2) are described by the color-singlet nonrelativistic wave functions. We find that for these decays (except χc1) there are infrared divergences arising from nonfactorizable vertex corrections as well as… (More)
