Measurement of Lepton Mass Squared Moments in $B\to X_c\ell {\bar{\nu }}_{\ell }$ Decays with the Belle II Experiment

Belle II Collaboration

We present measurements of the first to fourth moments of the lepton mass squared $q^2$ of \mbox{$B\to X_c\ell {\bar{\nu }}_{\ell }$} decays for $\ell =e,\mu$ and with $X_c$ a hadr…
