Semileptonic $B$-meson decays including $b\to c$ anomalies at Belle II

We present recent measurements of semileptonic $B$-meson decays using a data sample collected at the $\mathrm{{\rm Y}}(4S)$ resonance by the Belle II experiment corresponding to an integrated luminosity of $189{\mathrm{f}\mathrm{b}}^{-1}$. We determine the CKM-matrix elements $\mathrm{\mid }{V}_{\mathrm{c}\mathrm{b}}\mathrm{\mid }$ using untagged $B^0\to D^{\ast -}{\mathrm{\ell }}^{+}{\nu }_{\mathrm{\ell }}$ decays and $\mathrm{\mid }{V}_{\mathrm{u}\mathrm{b}}\mathrm{\mid }$ using untagged $B^0\to {\pi }^{-}{\mathrm{\ell }}^{+}{\nu }_{\mathrm{\ell }}$ decays. We test light lepton universality in two new analyses using hadronically tagged events. We report the first measurement of a complete set of five different angular distributions using $B^0\to D^{\ast -}{\mathrm{\ell }}^{+}{\nu }_{\mathrm{\ell }}$ decays and we measure the branching fraction ratio of inclusive $B\to Xe{\bar{\nu }}_e$ and $B\to X\mu {\bar{\nu }}_{\mu }$ decays.
