Break of Forward Slope and Dip in Proton-Proton Differential Cross Sections

Abstract

Proton-proton scattering in the CERN-ISR energy region is analysed in terms of the Chou-Yang type diffraction model. It is shown that the break structure and the position of dip strongly correlate to each other. The “Born” amplitude, or the Fourier-Bessel transform of the eikonal is seen to be approaching to the proton electromagnetic form factor as the total energy increases. Prediction of the total cross section σ_t and the forward slope b at E_cm=62 GeV is attempted and 44.8 ≲σ_t ≲44.7 mb and 13.2 ≲b ≲13.8 (GeV/c)^-2 are obtained. Some remarks are made about the Kuroda-Miyazawa model.
