Abstract
The recent discovery of a large [Formula presented] violating asymmetry in [Formula presented] mode has prompted us to seach for the associated [Formula presented] decay mode in the KTeV-E799 experiment at Fermilab. In [Formula presented] [Formula presented] decays, one candidate event has been observed with an expected background of 0.3 event, resulting in an upper limit for the [Formula presented] branching ratio of [Formula presented] at the 90% C.L.
