New results on inclusive $B\to X_{u} \ell ν$ decay from the Belle experiment

12 Jan 2021  ·  Lu Cao ·

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 on partial branching fractions and the CKM matrix element $|V_{ub}|$ are presented.
