Description
In this talk we present our BK solution to next-to-leading order approach (NLO) and compare with the experimental HERA data. This approach includes the re-summed NLO corrections to the kernel of the evolution equation, the impact
parameter dependence of the saturation scale in accord with the Froissarrt theorem as well as the non-linear corrections. We successfully describe the experimental data with the quality, which is not worse, than in the leading order fits with larger number of the phenomenological
parameters. It is demonstrated, that the data could be described, taking into account both the diffusion on ln(kT ), which stems from perturbative QCD, and the Gribov’s diffusion in impact parameters.
