Abstract
We study charmless meson decays to the final state using a data sample collected at the resonance with the Belle detector at the KEKB asymmetric-energy collider. There are significant signals found with the mass peaking near threshold. The observed branching fraction for nonresonant is with a significance of 9.1 standard deviations. We also observe the intermediate three-body decay with a branching fraction of and a significance of 9.5 standard deviations, and find a hint of a signal. No other intermediate three-body decay is found in this study.
