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∂lnQ2 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∂lnQ2 do not allow one to discriminate between the various approaches, in spite of their very different construction.
