CHOU-YANG-GLAUBER MODEL FOR THE PP AND P(P)OVER-BAR SCATTERING

Scattering cross-sections of proton-proton and proton-antiproton are i nvestigated with recourse to the Chou-Yang-Glauber model which is modi fied by adding an extra term so as to fit the data of differential cro ss-sections. The experimental data are reproduced very well in the ene rgy 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 rho parameters are ca lculated for the multi-TeV region by extrapolating the parameters abov e 1.8 TeV. The results coincide with that obtained by the dispersion t heoretic parametrization. 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.
