摘要: The radiative decays of the charged and neutral ρ meson are discussed assuming that decay vertices dominated by low-mass ππ ωπ intermediate states. transitions ρ→π+γ, ρ0→π++π−+γ, ρ0→π0+π0+γ, ρ+,−→π+,−+π0+γ ρ0→η+γ considered in detail. probability for emission a photon with energy exceeding 15 MeV process ρ0→π++π−+γ relative to 2π is found be 1.7×10−2, indicating (2π+γ) width comparable or greater than (π+γ) one. internal bremsstrahlung direct processes included calculation various partial widths.
