Abstract

We have carried out at Fermilab the first search for the lepton-family number violating decay K_L → π⁰μ^±e^∓. There were no events observed. By normalizing to K_L → π⁺π^-π⁰ decays collected simultaneously, the 90% confidence level upper limit on 1/2[BR(K_L → π⁰μ⁺e^-) + BR(K_L → π⁰μ^-e⁺)] was determined to be 3.1 × 10^-9.
