摘要：
We report on the first Belle II measurements of branching fractions and CP-violating charge asymmetries in charmless B decays. We use 34.6 fb(-1) from electron-positron collisions collected in 2019 and 2020 at the Y(4S) resonance. The results are compatible with known values and show performance already comparable with that of Belle.
