摘要

Physics and Astronomy (all)
We report the first observation of the charmless two-body mode [Formula presented] decay, and a new measurement of the branching fraction for the [Formula presented] decay. The measured branching fractions are [Formula presented] and [Formula presented]. We also measure the partial rate asymmetry of [Formula presented] decays and obtain [Formula presented]. The results are based on a data sample of [Formula presented] collected on the [Formula presented] resonance by the Belle detector at the KEKB [Formula presented] collider. © 2002 The American Physical Society.
