We report the results of a search for [Formula Presented] based on a data set of [Formula Presented] data collected at the [Formula Presented] resonance with the Belle detector at the KEKB asymmetric [Formula Presented] collider. No substantial signal is found, and we set the branching fraction upper limit [Formula Presented] at 90% confidence level.
