Abstract

The KS → γγ decay rate has been measured with the NA48 detector using a high intensity short neutral beam from the CERN SPS. The measured branching ratio BR(K_S → γγ) = (2.78 ± 0.06_stat ± 0.04_syst) x 10^-6, obtained from 7461 ± 172 K_S → γγ events, is significantly higher than the O(p⁴) prediction of chiral perturbation theory. Using a K_L beam the ratio Γ(K_L → γγ)/Γ(K_L → π⁰π⁰π⁰) = (2.81 ± 0.02syst) ×10^-3 has been measured.
