Early charmless B physics at Belle II
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 (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.
