Abstract
We study charmless hadronic decays of charged mesons to the final states and using a data sample that contains pairs and was collected at the resonance with the Belle detector at the KEKB asymmetric-energy collider. For , the measured branching fraction and direct asymmetry are and , respectively. In the absence of a statistically significant signal for , we obtain a 90% confidence-level upper limit on its branching fraction as .
