Probing factorization in the color-suppressed decay B→ψ(2S)+K(K*)

In order to probe the factorization hypothesis in the color-suppressed decays B→ψ(2S)+K(K*) we have studied three ratios R≡B(B→ψK)/B(B→ψ(2S)K), R'≡B(B→ψK*)/B(B→ψ(2S)K*), and PL'≡ΓL(B→ψ(2S)K*)/Γ(B→ψ(2S)K*) in several scenarios for the q2 dependence of the form factors involved. We find that measurements of R and R', which exist, do not yield scenario-independent tests of factorization. However, the predicted range of PL' in all scenarios lies in a narrow range, 0.50 approx-lt PL'≤0.67, and could test factorization
