Abstract

We examine the latest HERA experimental measurements of the Q2 logarithmic derivative of the proton structure function. We analyze the characteristics of DGLAP with and without screening, as well as a Regge type model, and compare their predictions to all available data on ∂F2/∂In Q2 including those for fixed W. Our results show that the present data can be described in pQCD taking into account shadowing corrections. However, such a description cannot be considered a conclusive signal of gluon saturation since the experimental data on ∂F2/∂In Q2 do not allow one to discriminate between the various approaches, in spite of their very different construction.
