Can B > J/ψ K(K^{*}) decays be described by factorization?
Abstract
The new measurements of B > J/ψ K(K^{*}) decays by CDF and CLEO indicate that the production ratioR and the fraction of longitudinal polarization Γ_{L}/Γ are smaller than the previous results. In conjunction with the new result of parityodd transverse polarization in B > J/ψK^{*}, we found a minimal modification to the factorization hypothesis: While the data of B > J/ψ K^{*} can be accommodated in the factorization approach with nonfactorizable terms χ_{A1} = χ_{A2} = χ_{v}  χ of ~ 15% to nexttoleading order, the result of R measurement requires that the nonfactorizable effect χ_{F1} on B > J/ψ K be slightly larger than χ. Therefore, the effective parameter a^{eff}_{2} is not universal even for B >J /ψ K(K^{*}) decays. We have generalized the considerations to B > ψ(2S)K(K^{*}) and B_{s} >J /ψ φ and found that the predictions are in agreement with currently available data.
