Measurement of D0→πlν(Klν) Form Factors and Absolute Branching Fractions

L. Widhalm, K. Abe, I. Adachi, H. Aihara et autres

Using a $282\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected by the Belle experiment at the KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider, we study ${D}^{0}$ decays to ${K}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu}$ and ${\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}\ensuremath{\nu}$ final states. The ${D}^{0}$ flavor and momentum are tagged through a full reconstruction of the recoiling charm …

Measurement of Branching Fractions for B→ηcK(*) Decays

F. Fang, T. Hojo, K. Abe, K. Abe et autres

We report measurements of branching fractions for charged and neutral $B\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}K$ decays where the ${\ensuremath{\eta}}_{c}$ meson is reconstructed in the ${K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, ${K}^{*0}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, and $p\overline{p}$ decay channels. The neutral ${B}^{0}$ channel is a $CP$ eigenstate and can be used to measure the …

Study of →Dππ decays

A. Satpathy, K. Abe, R. Abe, K. Abe et autres

We report on a study of B 0 →D (∗)0 π + π − decays using 29.1 fb −1 of e + e − annihilation data recorded at the ϒ(4 S ) resonance with the Belle detector at the KEKB storage ring. …

Observation of B¯0→D(*)0pp¯

K. Abe, Riichiro Abe, Byoung Sup Ahn, H. Aihara et autres

The $B$ meson decay modes $B\ensuremath{\rightarrow}Dp\overline{p}$ and $B\ensuremath{\rightarrow}{D}^{*}p\overline{p}$ have been studied using $29.4\text{ }\mathrm{f}{\mathrm{b}}^{\mathrm{\ensuremath{-}}\mathrm{1}}$ of data collected with the Belle detector at KEKB. The ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{0}p\overline{p}$ and ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{*0}p\overline{p}$ decays have been observed for the first time with branching fractions $\mathcal{B}({\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{0}p\overline{p})=(1.18\ifmmode\pm\else\textpm\fi{}0.15\ifmmode\pm\else\textpm\fi{}0.16)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and $\mathcal{B}({\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{*0}p\overline{p})=({1.20}_{\ensuremath{-}0.29}^{+0.33}\ifmmode\pm\else\textpm\fi{}0.21)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$.
