Abstract

We report on a search for the rare decay K_L → π⁰νν + ̄ in the KTeV experiment at Fermilab. We searched for two-photon events whose kinematics were consistent with an isolated π⁰ coming from the decay K_L → π⁰νν + ̄. One candi date event was observed, which was consistent with the expected level of background. An upper limit on the branching ratio was determined to be B(K_L → π⁰νν + ̄) < 1.6 × 10^-6 at the 90% confidence level.
