摘要

The K^+→π ^+π ^0π ^0γ decay is observed by the OKA collaboration. About 60 events of the decay observed with signal:noise ≈ 1 . The branching ratio obtained by normalization to K^+→π ^+π ^0π ^0 is measured to be (3.7 ± 0.9(stat) ± 0.3(syst))× 10^-6 for E_γ^*>10 MeV . The branching ratio, γ energy spectrum and angular distribution are consistent with ChPT prediction.
