We report a search for charmless hadronic decays of charged $ B $ mesons to the final

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