Abstract

The K_L→π^±π⁰e ^∓ν_e(ν̄_e) decay was investigated with the NA48 detector at CERN SPS using a beam of long-lived neutral kaons. The branching ratio Br(K_L→π ^±π⁰e^∓ν _e(ν̄_e))=(5.21±0.07_stat±0. 09_syst)×10^-5 was fixed from a sample of 5464 events with 62 background events. The form factors f̄_s, f̄_p, λ_g and h̄ were found to be in agreement with previous measurements but with higher accuracy. The coupling parameter of the chiral Lagrangian L₃=(-4.1±0.2)×10 ^-3 was evaluated from the data.
