Abstract

Several 132 K_L → e⁺e^- μ⁺ μ^- events were observed from the 1997 and 1999 runs of the KTeV experiments, with an estimated background of 0.8 events. In the first measurement of the parameter α using this decay mode, it was found that α=-1.59±0.37. No evidence was found for CP-violating contributions to the K_Lγ*γ* interaction.
