Saturation effects in diffractive scattering at LHC energies

Abstract

Unitarization schemes can be reduced to non-linear equations which saturate at small $b$ the evolution of the elastic amplitude with $s$, and which mimic parton saturation in the non-perturbative regime. These equations enable us to study the effect of saturation on total and elastic cross sections for various models, and to evaluate the uncertainties on $\ddot{I}{ƒ}_{tot}$ and $\ddot{I}(s,t)$ at the LHC in the presence of a hard pomeron.
