Description
The lepton flavour universality predicted by the Standard Model is challenged by various measurements of b-hadron decays involving tau and light leptons. The Belle II experiment started recording first collision data in Spring 2019 and offers a unique laboratory to study lepton flavour universality in leptonic and semileptonic decays of B mesons at high precision. In this talk, we report the status of establishing first measurements of $B \to \tau \bar \nu_\tau$, $B \to \mu \bar \nu$, and $B \to D^{(*)} \tau \bar \nu_\tau$ processes using the available Belle II data and discuss the future potential of investigating the $R(D^{(*)})$ anomaly.
