Description
The observed rate of semitauonic $B$ decays has been consistently above expectations since these decays were first measured. Significant differences between the forward-backward asymmetry in $B \to D^*e \nu$ and $B \to D^* \mu \nu$ were also reported. Belle II data are well suited to probe these anomalies. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two $B$ mesons in the event offer high precision. This talk presents recent Belle II results on lepton-flavor universality tests.
