摘　　要：This work presents the subtraction procedure and the Regge cut in the logarithmic Regge pole approach.The subtraction mechanism leads to the same asymptotic behavior as previously obtained in the non-subtraction case.The Regge cut,in contrast,introduces a clear role to the non-leading contributions for the asymptotic behavior of the total cross-section.From these results,some simple parameterization is introduced to fit the experimental data for the proton-proton and antiproton-proton total cross-section above some minimum value up to the cosmic-ray.The fit parameters obtained are used to present predictions for the ρ(s)-parameter as well as to the elastic slope B(s)at high energies.
