573. Determination of $|V_{cb}|$ from $B\to D\ell\nu$ decays using 2019--2021 Belle II data / Philipp Horak ; Christoph Schwanda [BELLE2-CONF-PH-2022-010]
19 October 2022

We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{cb}$ using the decay $B\to D\ell\nu$ based on $e^+e^-\to\Upsilon(4S)$~data recorded by the Belle II detector and corresponding to \lumi of integrated luminosity. [...]

574. Improved Selective Background Monte Carlo Simulation at Belle II with Graph Attention Networks and Weighted Events / Boyang Yu [BELLE2-POSTER-CONF-2022-003]
24 October 2022
/ ACAT 2022
When measuring rare processes at Belle II, a huge luminosity is required, which means a large number of simulations are necessary to determine signal efficiencies and background contributions. [...]
