New results on inclusive $B\to X_u\ell \nu$ decay from the Belle experiment

Abstract

We report on the measurement of inclusive charmless semileptonic B decays $B\to X_u\ell \nu$. The analysis makes use of hadronic tagging and is performed on the full data set of the Belle experiment comprising 772 million $B\bar{B}$ pairs. In the proceedings, the preliminary results of measurements of partial branching fractions and the CKM matrix element $|V_{ub}|$ are presented.
