Abstract
We report on the extension of the data fitting considering the QCD inspired model based on the summation of gluon ladders applied to the scattering. In lines of a two Pomeron approach, the structure function has a hard piece given by the model and the remaining soft contribution: a soft Pomeron and non-singlet content. In this contribution, we carefully estimate the relative role of the hard and the soft pieces from a global fit in a large span of and .
