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 : $χ_{F1} = χ_{A1} = χ_{A2} = χ_{V} = χ$. We consider various phenomenological models to compare their theoretical predictions with the recent CLEO II experimental measurements.9 pages, no figure, Contributed note at BaBar Yellow BooksHigh Energy Physics - Phenomenologytext
