Abstract:

In this talk, I will argue that the HERA experimental data show that the typical parameter (

\kappa

) responsible for the value of the shadowing corrections (SC) in DIS is so large that the BFKL Pomeron is hidden under SC. The SC turn out to be large enough but mostly for the gluon structure function which is not well determined by the available experimental data and by the current theoretical procedure.
