Small-x dipole evolution beyond the large-Nc limit

Abstract

We present a method to include colour-suppressed effects in the Mueller dipole picture. The model consistently includes saturation effects both in the evolution of dipoles and in the interactions of dipoles with a target in a frame-independent way. When implemented in a Monte Carlo simulation together with our previous model of energy-momentum conservation and a simple dipole description of initial state protons and virtual photons, the model is able to reproduce to a satisfactory degree both the γ*p cross sections as measured at HERA as well as the total pp cross section all the way from ISR energies to the Tevatron and beyond. © SISSA 2007.
