Factorization in Color-Suppressed B Meson Decays

Abstract

We summerize the status of factorization hypothesis in the color-suppressed B meson decays : $B\to J/\psi K^{(\ast )}$. 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.
