Observation of the decay Υ(4S)→Υ(1S)π+π−

M. Shapkin, K. Abe, K. Abe, I. Adachi et autres

We study transitions between $\ensuremath{\Upsilon}$ states with the emission of charged pions using $477\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The measured product branching fraction $\mathcal{B}(\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}\ensuremath{\Upsilon}(1S){\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})\ifmmode\times\else\texttimes\fi{}\mathcal{B}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})=(4.42\ifmmode\pm\else\textpm\fi{}0.81(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.56(\mathrm{sys}))\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$. When the PDG value for $\mathcal{B}(\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})$ is …

Moments of the electron energy spectrum and partial branching fraction of B→Xceν decays at the Belle detector

P. Urquijo, E. L. Barberio, K. Abe, I. Adachi et autres

We report a measurement of the inclusive electron energy spectrum for charmed semileptonic decays of $B$ mesons in a $140\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. We determine …

Improved measurements of branching fractions and CP partial rate asymmetries for B→ωK and B→ωπ

C.-M. Jen, P. Chang, K. Abe, I. Adachi et autres

We report improved measurements of $B$ to pseudoscalar-vector decays containing an $\ensuremath{\omega}$ meson in the final state. Our results are obtained from a data sample that contains $388\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs accumulated at the $\ensuremath{\Upsilon}(4S)$ resonance, with the Belle detector at the KEKB …

First observation of the decay τ−→ϕK−ντ

K. Inami, K. Abe, I. Adachi, H. Aihara et autres

We present the first observation of τ lepton decays to hadronic final states with a ϕ -meson. This analysis is based on 401 fb −1 of data accumulated at the Belle experiment. The branching fraction obtained is B ( τ − → …
