Nonfactorization in Cabibbo-Favored B Decays

We assume universal values for the color-singlet (${ϵ}_1$) and color octet (${ϵ}_8$) nonfactorization parameters in B Decays. Two sets of color-favored processes and one set of color-suppressed processes were used to give quantitative estimates of these parameters. It has been found (by calculating the branching ratios for a large number of Cabibbo-favored B Decays) that the values ${ϵ}_1({\mu }_0)=-0.06+\mathrm{/}-0.03$ and ${ϵ}_8({\mu }_0)=0.12+\mathrm{/}-0.02$ improve significantly the predictions of the factorization model.
