We summerize the status of factorization hypothesis in the color-suppressed B meson decays : $B \to J/\psi K^{(*)}$. We present the general formalism for decay rates and polarization fractions with considering all possible non-factorizable…

Using 3.1 fb$^{-1}$ of data accumulated at the $\Upsilon$(4S) by the CLEO-II detector, corresponding to 3.3 million $B\bar{B}$ pairs, we have searched for the color-suppressed $B$ hadronic decay processes: $\bar{B}^0 \to D^0 (D^{*0}) X^0$,…

Recent experimental results on the color-suppressed nonleptonic decays B^0 -> D^{(*)0} pi^0 provide evidence for a failure of the naive factorization model and for sizeable relative strong-interaction phases between class-1 and class-2 B ->…

We report preliminary results of an experimental investigation of the color-suppressed decays bar{B^0} --> D^0 pi^0, D^0 eta, and D^0 omega. We measure the branching fractions B (bar{B^0} --> D^0 pi^0) = (2.89 +/- 0.29 (stat.) +/- 0.38…

Color-suppressed decays of $B$ mesons to final states with $\psi(2S)$ mesons have been observed with the CLEO detector. The branching fractions for the decays $B^+ \to \psi(2S) K^+$, $B^+ \to \psi(2S) K^*(892)^+$, $B^0 \to \psi(2S) K^0$,…

We present a detailed study of non-leptonic two-body decays of B mesons based on a generalized factorization hypothesis. We discuss the structure of non-factorizable corrections and present arguments in favour of a simple phenomenological…

We investigate the possibility of testing factorization hypothesis in non-leptonic exclusive decays of B-meson. In particular, we considered the non factorizable \bar{B^0} -> D^{(*)+} D_s^{(*)-} modes and \bar{B^0} -> D^{(*)+} (\pi^-,…

The decay modes of the type $B \rightarrow \pi \, \pi $ are dynamically different. For the case $\bar{B_{d}^0} \rightarrow \, \pi^+ \pi^- $ there is a substantial factorized contribution which dominates. In contrast, the decay mode…

In order to probe the factorization hypothesis in color-suppressed $B \rightarrow \psi (2S) + K (K^*)$ decays we have studied three ratios: $ R \equiv B (B \rightarrow \psi K) / B (B \rightarrow \psi(2S) K)$, $ R' \equiv B (B \rightarrow…

We propose studying the mechanism of factorization in exclusive decays of the form B->D(*)X by examining the differential decay rate as a function of the invariant mass of the light hadronic state X. If factorization works primarily due to…

We show that the factorization assumption in color-suppressed $B$ meson decays is not ruled out by experimental data on $B \ra K(K^*) + J/\Psi(\Psi^{'})$. The problem previously pointed out might be due to an inadequate choice of hadronic…

Improved $B$ meson decay data have permitted more incisive tests of factorization predictions. A concurrent benefit is the ability to constrain the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$. Using a simultaneous fit to…
