Recent Belle II results related to B anomalies
Semileptonic ๐ต-meson decays involving the quark transition $b\to cl\nu$ provide excellent sensitivity to probe potential lepton-flavour universality violation. This work introduces two recent measurements related to tests of light-lepton flavour universality using a data sample collected at the $\Upsilon$(4๐) resonance on the Belle II experiment corresponding to an integrated luminosity of 189fb$^{โ1}$. Measurement of the ratio of the branching fractions of inclusive $B\to Xe\nu_e$ and $B\to X\mu\nu_{\mu}$ decays and measurement of angular asymmetries of $B^0\to D^{*-}l\nu$ decays agree well with standard model expectation.
