【 摘 要 】

We consider the effect of an energy-dependent dipole form factor in the high-energy behavior of the forward amplitude. The connection between the semihard parton-level dynamics and the hadron-hadron scattering is established by an eikonal QCD-based model. Our results for the proton-proton (pp) and antiproton-proton (pp) total cross sections, σtotpp, pp, obtained using the CTEQ6L1 parton distribution function, are consistent with the recent data from the TOTEM experiment.
