Study of $χ_{b J} (n P) \to ω Υ (1 S)$ at Belle

Belle Collaboration, A. Abdesselam, I. Adachi +470

We report results from a study of hadronic transitions of the $χ_{b J} (n P)$ states of bottomonium at Belle. The $P$ -wave states are reconstructed in transitions to the $Υ (1 S)$ with…

Observation of Transverse $Λ/ Λ ˉ$ Hyperon Polarization in $e^{+} e^{-}$ Annihilation at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +445

We report the first observation of the polarization of $Λ/ Λ ˉ$ hyperons transverse to its production plane in $e^{+} e^{-}$ annihilation. We observe a significant polarization that ri…

Measurement of Azimuthal Modulations in the Cross-Section of Di-Pion Pairs in Di-Jet Production from Electron-Positron Annihilation

A. Abdesselam, I. Adachi, K. Adamczyk +418

We present an extraction of azimuthal correlations between two pairs of charged pions detected in opposite jets from electron-positron annihilation. These correlations may arise fr…

Measurement of the $B ˉ \to X_{s} γ$ Branching Fraction with a Sum of Exclusive Decays

Belle Collaboration, T. Saito, A. Ishikawa +179

We use 772 $\times 1 0^{6}$ $B B ˉ$ meson pairs collected at the $Υ (4 S)$ resonance with the Belle detector to measure the branching fraction for $B ˉ \to X_{s} γ$ . Our me…

Measurement of the branching fraction of $B^{+} \to τ^{+} ν_{τ}$ decays with the semileptonic tagging method and the full Belle data sample

Belle Collaboration, A. Abdesselam, I. Adachi +392

We report a measurement of the branching fraction of $B^{+} \to τ^{+} ν_{τ}$ decays using a data sample of $772 \times 1 0^{6} B B ˉ$ pairs, collected at the $Υ (4 S)$ resonance with the…

Observation of $e^{+} e^{-} \to π^{+} π^{-} π^{0} χ_{b J}$ and search for $X_{b} \to ω Υ (1 S)$ at $s \sim 10.867$ GeV

Belle Collaboration, X. H. He, C. P. Shen +158

The $e^{+} e^{-} \to π^{+} π^{-} π^{0} χ_{b J}$ ( $J = 0, 1, 2$ ) processes are studied using a 118~fb $^{- 1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $Υ (10860)$ ener…
