Abstract
We present the results of a search for the decay in a data sample of decays using the BABAR detector. Certain extensions of the standard model predict measurable levels of this otherwise rare decay. We reconstruct fully one neutral meson and seek evidence for the signal decay in the rest of the event. We find no evidence for signal events and obtain at the 90% confidence level.
