Nonfactorization in Cabibbo-Favored B Decays

Abstract

We assume universal values for the color-singlet (${\epsilon }_1$) and color octet (${\epsilon }_8$) 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 ${\epsilon }_1({\mu }_0)=-0.06+/-0.03$ and ${\epsilon }_8({\mu }_0)=0.12+/-0.02$ improve significantly the predictions of the factorization model.
