We point out that the decay modes B^0 --> D_s^+ D_s^- and B_s^0 --> D^+ D^- have no factorized contribution. At quark level these dacays can only proceed through the annihilation mechanism, which in the factorized limit give zero amplitude…

Using about 23M $B \bar B$ events collected in 1999-2000 with the BABAR detector, we report on the decays $B \to D^{(*)}\bar D^{(*)}K$ and $B^0 \to D^{*+}D^{*-}$. The branching fractions of the low background decay modes $B \to D^{(*)}\bar…

We present a study of the decay B- -> D*0 K*- based on a sample of 86 million Upsilon(4S) -> BBbar decays collected between 1999 and 2002 with the BaBar detector at the PEP-II asymmetric-energy B-Factory at SLAC. We measure the branching…

This article describes improved measurements by CLEO of the $B^0 \to D_s^+ D^{*-}$ and $B^0 \to D_s^{*+} D^{*-}$ branching fractions, and first evidence for the decay $B^+ \to D_s^{(*)+} \bar{D}^{**0}$, where $\bar{D}^{**0}$ represents the…

While the factorization assumption works well for many two-body nonleptonic $B$ meson decay modes, the recent measurement of $\bar B\to D^{(*)0}M^0$ with $M=\pi$, $\rho$ and $\omega$ shows large deviation from this assumption. We analyze…

We report the first observation of color-suppressed $\bar{B}{}^0 \to D^0 \pi^0$, $D^{*0} \pi^0$, $D^{0} \eta$, and $D^{0}\omega$ decays and evidence for $\bar{B}{}^0 \to D^{*0} \eta$ and $D^{*0}\omega$. The branching fractions are found to…

We present two recent results obtained by the CDF collaboration at the Tevatron collider. New Cabibbo suppresed B_s decay modes have been observed using 5.9 inverse fb of data: B_s-> J/psi Ks and B_s->J/psi K*0. We report also on masurement…

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…

The four decay modes $D^{0}\to\phi\pi^{0}$, $D^{0}\to\phi\eta$, $D^{+}\to\phi\pi^{+}$, and $D^{+}\to\phi K^{+}$ are studied by using a data sample taken at the centre-of-mass energy $\sqrt{s} = 3.773$~GeV~with the BESIII detector,…

Two-body decays of B mesons are studied by decomposing their amplitude into a sum of factorizable and non-factorizable ones. The former is estimated by using the naive factorization while the latter is calculated by using a hard pion (or…
