We report the first evidence for the transition with a significance of 3.5 standard deviations. The decay branching fraction is measured to be , which is noticeably smaller than expected. We also set upper limits on transitions of , and , at the 90% confidence level. These results are obtained with a data sample collected near the resonance with the Belle detector at the KEKB asymmetric-energy collider. Published by the American Physical Society2024
