Abstract: We report on the first measurements of branching fractions, CP-violating charge asymmetries, and longitudinal polarization fractions in charmless 𝐵 decays at the Belle II experiment. We use a sample of electron-positron collisions collected in 2019 and 2020 at the Υ(4𝑆) resonance that corresponds to 34.6 fb−1 of integrated luminosity. The results are compatible with the known values, which indicates a good understanding of detector performance.
