Abstract
loose selection on the tag-side multivariate classifier, the calibration factors are 0.65± 0.02 and 0.83 ± 0.03 for tag-side + and 0 mesons, respectively. The calibrated hadronic tag-side decay modes are used to measure the branching fractions B( 0 → ∗+l− āl) = (4.45 ± 0.41(stat) ± 0.27(sys) ± 0.45(cs)) × 10−2 and B( 0 → c+l− āl) = (1.62 ± 0.42(stat) ± 0.07(sys)) × 10−4 in 34.6 fb−1 of Belle II data.
