TESTS OF FACTORIZATION IN COLOR SUPPRESSED NONLEPTONIC B DECAY MODES,

Abstract

We propose a number of tests of factorization for the color-suppressed nonleptonic decay channels: $B\to K^{(\ast )}{\eta }_c$ and $B\to K^{(\ast )}{\eta }_c^{\prime }$. The relevant leptonic constants and form factors are calculated within the QCD sum rules approach.
