Abstract

We report the first observation of a [Formula presented] meson decay that is not accessible by a direct spectator process. The channel [Formula presented] is found in a sample of [Formula presented] [Formula presented] events, collected with the Belle detector at KEKB, with a branching fraction [Formula presented]. We also obtain evidence for the [Formula presented] decay with branching fraction [Formula presented]. This value may be used to extract a model-dependent value of [Formula presented].
