Observation of K*+*>*p*+*p*0*p*0*g Decay / A.V.Artamonov, V.N.Bychkov, G.D.Kekelidze, V.M.Lysan, B.Zh.Zalikhanov, [a.o.] // The European Physical Journal C [Electronic resource]. – 2024. – Vol. 84, No. 4. – P. 345. – URL: https://doi.org/10.1140/epjc/s10052-024-12674-0. – Bibliogr.: 12.

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&sup(−6) for E&sup(∗ )γ > 10 MeV. The branching ratio, γ energy spectrum and angular distribution are consistent with ChPT prediction.
