HIGH-ENERGY PREDICTIONS FOR PBARP AND PP ELASTIC-SCATTERING AND TOTAL CROSS-SECTIONS

Predictions for the s behavior at high energies are made for -pp and pp: the differential elastic scattering cross section d σ/dt vs. t, the squared 4-momentum transfer; the total elastic cross section σel; the nuclear slope parameter B; the curvature parameter C; ρ{variant}, the ratio of the real to the imaginary portion of the forward scattering amplitude; and the total cross section σtot. A hybrid approach is employed in order to gain reliable predictions. The energy dependence of ρ{variant} and σtot is fixed by fitting pp and -pp experimental data for ρ{variant} and σtot from 15 GeV to S-ppS energies, using analytic amplitudes. The other quantities are found using the Chou-Yang model, where the total, cross section is fixed from the fit. © 1990 Academia, Publishing House of the Czechoslovak Academy of Sciences.
