High-EnergyppScattering and Proton Substructure. IV

Results of a systematic analysis of high-energy $\mathrm{pp}$ elastic-scattering data in terms of a proton-substructure model are presented. The model satisfactorily describes differential cross sections over the entire momentum range 5-31 GeV/c and over the whole angular interval 0°-90°. $\mathrm{pp}$ elastic differential cross sections at future accelerator energies (70, 200, and 1600 GeV) are also predicted. The model indicates that the proton has two hadronic core distributions, which interact via exchange of vector mesons $\omega \left(\sim 800 \mathrm{MeV}\right)$ and ${\omega }^{\prime }\left(\sim 2200 \mathrm{MeV}\right)$. The rms radii of these distributions are 0.44 and 0.20 F.
