摘要：

Various predictions of the ρππ coupling constant fρ24π are discussed. A ρ+ρ′ meson dominance model is considered with Mρ′1600 MeV and Γρ′200 MeV. This model predicts a value of the S-wave π-N scattering length formula a1-a3 in better agreement with experiment than the ρ-dominance model when Γρ=128 MeV, and the modified Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin relation is well satisfied. © 1968 The American Physical Society.
