Abstract
We report the results of a search for the decay and based on an analysis of of data collected by the Belle detector at KEKB. No candidate events have been found. Upper limits on the branching fractions are calculated at the 90% confidence level: and A limit on the Pati-Salam leptoquark mass is obtained at the 90% confidence level.
