A preliminary measurement of branching fractions of the D0 and D+ mesons into the phi meson is reported. The result is based on a data sample of 22.3 pb-1 collected at the CM energy of 4.03 GeV with the BES detector operated at the BEPC…
We report the first observation of the decay B^0->D+-D*-+ with the Belle detector at the KEKB e^+e^- collider operated at the Upsilon(4S) resonance. The sum of branching fractions B(B^0->D+D*-)+B(B^0->D-D*+) is measured to be…
We present model-independent measurements of the branching fractions ${\cal B}(B^0\to D_s^{*+} D^{*-})$ and ${\cal B}(D_s^+ \to \phi \pi^+)$ based on 19.3 $\textup{fb}^{-1}$ of data collected by the $BABAR$ detector at the PEP-II $e^+e^-$…
We present the first amplitude analysis and branching fraction measurement of the decay $D^+_s\to \pi^+\pi^+\pi^-\pi^0\pi^0$, using $e^+e^-$ collision data collected with the BESIII detector at center-of-mass energies between 4.128 and…
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…
New precise measurements of $D_s^+$ and $D_s^{*+}$ meson production from $B$ mesons and $q\bar q$ continuum events near the $\Upsilon(4S)$ resonance are presented in this paper. Using the BABAR data recorded in 1999 and 2000 of 20.8…
By analyzing 2.93 fb$^{-1}$ of $e^+e^-$ annihilation data taken at the center-of-mass energy $\sqrt s=$ 3.773 GeV with the BESIII detector, we determine the branching fractions of the inclusive decays $D^+\to\phi X$ and $D^0\to\phi X$ to be…

Using an $e^+e^-$ annihilation data sample corresponding to an integrated luminosity of $2.93\,\rm fb^{-1}$ collected at the center-of-mass energy of 3.773\,GeV with the BESIII detector, we measure the absolute branching fractions of…
Using 5.2 fb-1 of e^+e^- annihilation data recorded with the BABAR detector at the PEP-II storage ring while operating on the Y(4S) resonance, a sample of fully reconstructed B^0 decays in the hadronic modes B^0 -> D^{*-}pi^+ and B^0 ->…
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,…
