Measurements of branching fractions and CP-violating charge asymmetries in charmless $B$ decays reconstructed in 2019--2020 Belle~II data

Belle II Collaboration, F. Abudinén, I. Adachi +544

We report on first measurements of branching fractions~( $B$ ) and CP-violating charge asymmetries~( $A$ ) in charmless $B$ decays at Belle~II. We use a sample of e…

Studies of the semileptonic $B ˉ^{0} \to D^{*+} ℓ^{-} ν ˉ_{ℓ}$ and $B^{-} \to D^{0} ℓ^{-} ν ˉ_{ℓ}$ decay processes with 34.6 fb $^{- 1}$ of Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +542

We report measurements of the $B ˉ^{0} \to D^{*+} ℓ^{-} ν ˉ_{l}$ and $B^{-} \to D^{0} ℓ^{-} ν ˉ_{l}$ processes using 34.6 fb $^{- 1}$ of collision events recorded by the Belle…

Measurement of the $B^{0}$ lifetime using fully reconstructed hadronic decays in the 2019 Belle II dataset

Belle II Collaboration, F. Abudinén, I. Adachi +534

This document presents the measurement of $B^{0}$ meson lifetimes using the 2019 Belle II dataset that corresponds to an integrated luminosity of $8.7 \pm 0.2$ fb $^{- 1}$ . Each candid…
