Hunting for new physics in $B$ meson $b\to u$ transitions: A fresh look with Belle II data

Pietro Colangelo, Fulvia De Fazio, Maria Letizia Di Cuia +1

We present an analysis of the decays $B^{-}\to {\ell }^{-}{\bar{\nu }}_{\ell }$, ${\bar{B}}^0\to {\pi }^{+}{\ell }^{-}{\bar{\nu }}_{\ell }$, and $B^{-}\to {\rho }^0{\ell }^{-}{\bar{\nu }}_{\ell }$ leveraging the precise measurem…
