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: $B \to K^{(*)} \; \eta_c$ and $B \to K^{(*)} \; \eta^\prime_c$. The relevant leptonic constants and form factors are calculated within the QCD sum rules approach.
