Abstract:

The pion-pion correlation effect is investigated, starting from the pion-pion scattering phase shifts which show the presence of a ρ meson in the I = L = 1 state and a strong attraction without resonance in the I = L = 0 state. By comparing with the OBEC amplitude, the roles of the pion-pion correlation and the normalization f+(+)0(0) = C0 in nucleon-nucleon scattering are clarified. Comparison with the empirical phase shifts in the iso-triplet state shows that C0 ∼ 0 and a rather small value of gw2 are probable and not inconsistent with the analysis of pion-nucleon scattering.
