Factorization in Color-Suppressed B Meson Decays

We summerize the status of factorization hypothesis in the color-suppressed B meson decays : $B \to J/\psi K^{(*)}$. We present the general formalism for decay rates and polarization fractions with considering all possible non-factorizable contributions which also include the color-octet contributions, and a new factorization scheme comes appear when the universality is exist : $\chi_{F1} = \chi_{A1} = \chi_{A2} = \chi_{V} = \chi$. We consider various phenomenological models to compare their theoretical predictions with the recent CLEO II experimental measurements.
