FORWARD-BACKWARD ASYMMETRIES

$\Delta (A_{FB}$) = (A${}^{{{\mathit \mu}}}_{FB}$ $−$ A${}^{{{\mathit e}}}_{FB}$) in ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{*-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$

1  ADACHI 2023H measurement is based on the angular asymmetries of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{*-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$ decays using explicit reconstruction of the ${{\mathit B}}$ tag. Other asymmetries from $\Delta\mathrm {(S_{3})}$, $\Delta\mathrm {(S_{5})}$, $\Delta\mathrm {(S_{7})}$, and $\Delta\mathrm {(S_{9})}$ are also reported.
