Proton-Proton Scattering for a Nucleon Isobar Model

Abstract

High-energy proton-proton scattering is calculated for a static interaction which includes coupling to excited nucleon states. The spin and isotopic spin dependence is taken from the strong coupling approximation of the charge-symmetric pseudoscalar meson theory; for the space dependence the Yukawa potential is used. The parameters of the interaction are chosen to fit the low-energy $p\ensuremath{-}p$ scattering data. The calculated high-energy scattering cross section is strongly anisotropic and thus in sharp conflict with the experimental results.
