Abstract
We report a search for the charmless hadronic decay with a data sample corresponding to an integrated luminosity of containing pairs. The data were collected by the Belle experiment running on the resonance at the KEKB collider. We measure a branching fraction , where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of at 90% confidence level. The signal has a significance of 3.0 standard deviations and constitutes the first evidence for this decay mode.
