Constraining the free parameter of the high parton density effects

Abstract

The high density parton effects are strongly dependent of the spatial gluon distribution within the proton, with radius RR, which cannot be derived from perturbative QCD. In this paper we assume that the unitarity corrections are present in the HERA kinematical region and constrain the value of RR using the data for the proton structure function and its slope. We obtain that the gluons are not distributed uniformly in the whole proton disc, but behave as concentrated in smaller regions.
