Description
The goal of this analysis is to make a precise measurement of the magnitude of the element |$V_{cb}$| of the Cabibbo–Kobayashi–Maskawa matrix based on B-decays to the exclusive final state $D^{*-} l^+ \nu_l$. We will explain how this new measurement addresses several limitations of previous determinations and will help to clarify the experimental status of |$V_{cb}$|. The first steps are to measure the branching fraction and kinematic variables of the decay -- preliminary results will be presented. This analysis is based on the data recorded by the Belle II experiment at the SuperKEKB collider.
