摘要：

We perform a global fit to the inclusive structure function considering a QCD-inspired model based on the summation of gluon ladders describing the ep scattering. In line with a two-pomeron approach, the structure function F-2 has a hard piece given by the model and the remaining soft contributions: the soft. pomeron and non-singlet content. We have investigated several choices for the soft pomeron and its implication in the data description. In particular, we carefully estimated the relative role of the hard and the soft contributions in a large span of x and Q(2).
