Determination of $|V_{cb}|$ from $B\to D\ell \nu$ decays using 2019-2021 Belle II data

Belle II collaboration, F. Abudinén, I. Adachi +590

We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{cb}$ using $B\to D\ell \nu$ decays. The result is based on $e^{+}{e}^{-}\to {\rm Y}(4S)$ data…
