Description
We search for the rare decay in a sample of electron-positron collisions at the ϒ(4S) resonance collected with the Belle II detector at the SuperKEKB collider. We use the inclusive properties of the accompanying meson in ϒ(4S)→BB¯ events to suppress background from other decays of the signal candidate and light-quark pair production. We validate the measurement with an auxiliary analysis based on a conventional hadronic reconstruction of the accompanying meson. For background suppression, we exploit distinct signal features using machine learning methods tuned with simulated data. The signal-reconstruction efficiency and background suppression are validated through various control channels. The branching fraction is extracted in a maximum likelihood fit. Our inclusive and hadronic analyses yield consistent results for the branching fraction of and …
