Determination of $|V_{cb}|$ using ${\overline{B}}^0\to D^{\ast +}{\ell }^{-}{\bar{\nu }}_{\ell }$ decays with Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +416

We determine the CKM matrix-element magnitude $|V_{cb}|$ using ${\overline{B}}^0\to D^{\ast +}{\ell }^{-}{\bar{\nu }}_{\ell }$ decays reconstructed in $189{\mathrm{fb}}^{-1}$ of collision data collec…
