Abstract

We report on a search for [Formula presented] decays based on [Formula presented] [Formula presented] events collected with the Belle detector at KEKB. The [Formula presented] and [Formula presented] decays have been observed for the first time with the branching fractions [Formula presented] and [Formula presented]. No significant signal has been found for the [Formula presented] and [Formula presented] decay modes, and upper limits at 90% C.L. are presented. © 2003 The American Physical Society.
