First measurements on charmless $B$ decays at Belle II

High Energy Physics - Experiment 2021-03-16 v1

Abstract

We report on the first Belle II measurements of branching fractions and CP-violating charge asymmetries in charmless BB decays. We use 34.6 fb1^{-1} from electron-positron collisions collected in 2019 and 2020 at the Υ(4S)\Upsilon(4S) resonance. The results are compatible with known values and show performance already comparable with Belle.
