Pion-Nucleon Scattering and J=2 T=0 Pion-Pion Interaction

Abstract

The effect of the J=2, T=0, π–π interaction on the π–N invariant amplitude B⁽⁺⁾ is analyzed. It was found that the π–N scattering data is inconsistent with a J=2, T=0, π–π phase, due to δ₂⁰, which rises To above 13° around 650 MeV. From the data it is impossible to say whether the results correspond to a resonant phase or only a sharp peak in the corresponding absorptive part of the amplitude.
