Can B → Jψ K(K∗) decays be described by factorization?

The new measurements of B → Jψ K(K∗) decays by CDF and CLEO indicate that the production ratio R and the fraction of longitudinal polarization ΓLΓ are smaller than the previous results. In conjunction with the new result of parity-odd transverse polarization in B → Jψ K∗, we found a minimal modification to the factorization hypothesis: While the data of B → Jψ K∗ can be accommodated in the factorization approach with nonfactorizable terms χA1 = χA2 = χV ≡ χ of ∼ 15% to next-to-leading order, the result of R measurement requires that the nonfactorizable effect χF1 on B → Jψ K be slightly larger than χ. Therefore, the effective parameter a2eff is not universal even for B → Jψ K(K∗) decays. We have generalized the considerations to B → ψ(2S)K(K∗) and Bs → Jψ φ and found that the predictions are in agreement with currently available data.
