Abstract

We have observed the decay (Formula presented) at the KTeV experiment at Fermilab. This decay presents a formidable background to the search for new physics in (Formula presented) The 1997 data yielded a sample of 4 signal events, with an expected background of (Formula presented) events. The branching ratio is (Formula presented) with (Formula presented) consistent with a QED calculation which predicts (Formula presented).
