Abstract

We report on preliminary measurements of branching fractions, charge-parity-violating asymmetries, and longitudinal polarization fractions in charmless bottom-meson decays from the Belle~II experiment. We use samples of electron-positron collisions collected in 2019 and 2020 at the Υ(4S) resonance, corresponding to integrated luminosities of up to 62.8 \rm fb^-1. The results are compatible with known values, indicating good understanding of early detector performance.
