Abstract | Persistent anomalies reported by various experiments in $b \rightarrow c$ and $b \rightarrow s\ell\ell$ transitions hint at possible violation of lepton-flavor universality. The Belle II experiment at the SuperKEKB collider probes the relevant effects using observables complementary to those explored elsewhere. This talk reports recent results from a sensitive search for $\bar{B}^{+} \rightarrow K^{+}\nu\bar{\nu}$ decays, and an inclusive determination of the branching fraction of bottom mesons into hadrons and tau leptons, relative to that into hadrons and light leptons. |
