Measurement of inclusive $B\to X_u\ell \hat{I}½$ partial branching fractions and $|V_{ub}|$ at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +419

A sample of 365 fb${}^{-1}$ of $e^{+}{e}^{-}\to \hat{I}\yen (4S)\to B\bar{B}$ data collected by the Belle II experiment is used to measure the partial branching fractions of charmless semileptonic…
