Evidence for $B^{+}\to K^{+}\hat{I}½\bar{\hat{I}}½$ decays

Belle II Collaboration, I. Adachi, K. Adamczyk +452

We search for the rare decay $B^{+}\to K^{+}\hat{I}½\bar{\hat{I}}½$ in a $362{\mathrm{fb}}^{-1}$ sample of electron-positron collisions at the $\hat{I}\yen (4S)$ resonance collected with the Belle II…
