Measurement of $B^{+}\to \ddot{I}{„}^{+}\hat{I}{½}_{\ddot{I}}„$ branching fraction with a hadronic tagging method at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +341

We present a measurement of the branching fraction of $B^{+}\to \ddot{I}{„}^{+}\hat{I}{½}_{\ddot{I}}„$ decays using $(387\pm 6)\times 10^6$ $\hat{I}\yen (4S)$ collected between 2019 and 2022 with the Belle II detector at t…
