Measurement of the branching fractions and $C P$ asymmetries of $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +582

We determine the branching fractions $B$ and $C P$ asymmetries $A_{CP}$ of the decays $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ . The result…

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…

First observation of exclusive $Υ (1 S)$ and $Υ (2 S)$ decays into light hadrons

Belle Collaboration, C. P. Shen, C. Z. Yuan +153

Using samples of 102 million $Υ (1 S)$ and 158 million $Υ (2 S)$ events collected with the Belle detector, we study exclusive hadronic decays of these two bottomonium resonances to the…
