Abstract

We reproduce the deep inelastic scattering measurements of the proton structure function at high energy from the dipole model in momentum space. To model the dipole-proton forward scattering amplitude, we use the knowledge of asymptotic solutions of the Balitsky-Kovchegov equation, describing high-energy QCD in the presence of saturation effects. The comparison of our results with previous analysis in coordinate space and possible extensions of our approach are discussed.
