Abstract
We report on a new measurement of the branching ratio using the KTeV detector. This analysis uses the full KTeV data set collected from 1997 to 2000. We reconstruct 139 events over a background of 14, which results in . This result supersedes the earlier KTeV measurement of this branching ratio.
