Extraction of form Factors from a Four-Dimensional Angular Analysis of $\overline{B}\to D^{\ast }{\ell }^{-}{\overline{\nu }}_{\ell }$

B. Dey

An angular analysis of the decay $\overline{B}\to D^{\ast }{\ell }^{-}{\overline{\nu }}_{\ell }$, $\ell \in \{e,\mu \}$, is reported using the full $e^{+}{e}^{-}$ collision data set collected by t…
