Abstract
We report measurements of charmless hadronic decays into the final state. The analysis uses a sample of pairs collected with the Belle detector at the KEKB asymmetric-energy collider at the resonance. The decay is observed for the first time; the significance is and the corresponding partial branching fraction for is . We also obtain the first evidence for with significance and for with significance. For the two-body decays and , the significances are and , respectively, and the upper limits on the branching fractions are and at 90% confidence level.
