Measurements of the branching fraction, polarization, and $C P$ asymmetry for the decay $B^{0} \to ω ω$

Belle Collaboration, Y. Guan, A. J. Schwartz +167

We present a measurement of $B^{0} \to ω ω$ , a charmless decay into two vector mesons, using 772 $\times 1 0^{6}$ $B B$ pairs collected with the Belle detector at the…

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 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…

Search for CP violating charge asymmetry in B^+ -> J/psi K^+ decays

K. Sakai, T. Kawasaki, H. Aihara +136

We present the result of a search for charge asymmetry in B^+ -> J/psi K^+ decays. The CP-violating charge asymmetry is measured to be A_CP(B^+ -> J/psi K^+) = [-0.76 +/- 0.50 (sta…
