57th Rencontres de Moriond 2023: Electroweak Interactions & Unified Theories

Abstract: Recent Belle II results of light-lepton flavor universality tests for b→c anomalies using semileptonic B decays are shown. This talk discusses the results of two measurements of $R(X_{e/\mu})$ and asymmetries of five angular observables between electron and muon, $\Delta\mathcal{A}_{x}(w)$, involving the hadronic tagging method in the Full Event Interpretation.
