Latest results on semileptonic and electroweak penguin decays at Belle II

The Belle~II Collaboration presents four new analyses: The measurement of $V_{ub}$ from $B\to \pi e{\nu }_e$ decays with a fit to the differential $q^2$ spectrum, the determination of $V_{cb}$ using a fit to the differential $w$ distribution from $B^0\to D^{\ast -}{\mathrm{\ell }}^{+}{\nu }_{\mathrm{\ell }}$ decays, and the measurement of $q^2$ moments in inclusive $B\to X_c\mathrm{\ell }{\nu }_{\mathrm{\ell }}$ decays. In all these analyses tag-side $B$ meson is reconstructed in a fully hadronic decay chain. The last result are branching fraction measurement of $B\to K^{\ast }{\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-}$ decays using an untagged approach.
