Description
Study of $B \to D_s^* h$ decays
We report a measurement of the branching fractions for $B^0 \to D_s^* h$ decays using a large sample of $B\bar{B}$ decays collected with the Belle detector at the KEKB asymmetric energy $e^+e^-$ collider.
Improved measurements of $B \to D_s K$ and $B \to D_s\pi$ branching fractions
We report improved measurements of the $B\to D_s K$ and $B\to D_s\pi$ branching fractions. The results are based on a large data sample recorded at the $\Upsilon$(4S) resonance by the Belle experiment at the KEKB asymmetric energy $e^+ e^-$ collider.
Measurement of $B \rightarrow D_s^{(*)} K\pi$ branching fractions
We report a measurement of the exclusive $B^+$ meson decay to the $D_s^{(*)-} K^+\pi^+$ final state using $657 \times 10^{6} B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We use $D_s^{*-}\to D_s^-\gamma$ and the $D_s^-\to \phi\pi^-$, $\bar{K}{}^*(892)^0 K^-$ and $K^0_S K^-$ decay modes for $D_s^{(*)}$ reconstruction to measure the following branching fractions: ${\cal B}(B^+\to D_s^-K^+\pi^+)$ and ${\cal B}(B^+\to D_s^{*-}K^+\pi^+)$.
Measurement of $B \to D_s K^0_s\pi$ and $B \to D_s K K$ branching fractions
We report a measurement of the exclusive $B$ meson decay to the $D_s K^0_s\pi$ and $D_s KK$ final states using $657 \times 10^{6} B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider.
