| Abstract: | We measure the branching fraction of the decay �−→�0�(770)− using data collected with the Belle II detector. The data contain 387 million � ¯ � pairs produced in �+�− collisions at the ϒ(4�) resonance. We reconstruct 8360±180 decays from an analysis of the distributions of the �− energy and the �(770)− helicity angle. We determine the branching fraction to be (0.939±0.021(stat)±0.050(syst))%, in agreement with previous results. Our measurement improves the relative precision of the world average by more than a factor of two. |
