1. Test of lepton flavor universality in inclusive semileptonic B decays at Belle II / Henrik Junkerkalefeld ; Peter Lewis ; Florian Bernlochner ; Jochen Dingfelder ; et al [BELLE2-CONF-PH-2022-004]
17 June 2022

We present the measurement of the ratio of branching fractions of inclusive semileptonic $B$ decays, $R(X_{e,\mu})=\mathcal{B}(B\to X e \nu)/\mathcal{B}(B\to X \mu \nu)$, with a hadronic tagged analysis using $189~\mathrm{fb}^{-1}$ of Belle II data..
