Early charmless $B$ physics at Belle II

High Energy Physics - Experiment 2021-03-19 v2

Abstract

We report on the first measurements of branching fractions, CP-violating charge asymmetries, and longitudinal polarization fractions in charmless BB decays at the Belle II experiment. We use a sample of electron-positron collisions collected in 2019 and 2020 at the Υ(4S)\Upsilon(4S) resonance that corresponds to 34.6 fb1^{-1} of integrated luminosity. The results are compatible with the known values, which indicates a good understanding of detector performance.
