Abstract
Scattering cross-sections of proton-proton an proton-antiproton are investigated with recourse to the Chou-Yang-Glauber model which is modified by adding an extra term so as to fit the data of differential cross-sections. The experimental data are reproduced very well in the energy region from a few GeV up to 1.8 TeV in the centre-of-mass system. The elastic and the total cross-sections and the ϱ parameters are calculated for the multi-TeV region by extrapolating the parameters above 1.8 TeV. The results coincide with that obtained by the dispersion theoretic parameterization. The total cross-section agrees with that of the cosmic-ray experiment. It is inferred that the asymptotic form of the differential cross-section is given by a simple formula.
