We find, within the pQCD dipole model for DIS processes, a rapid increasewith energy of the scale of parton momenta in the current fragmentation regionin the limit $s\to \infty$ and fixed $Q^2$ . We explain the equivalence betweenthe dispersion representation over $Q^2$ for LT pQCD zero angle amplitude of$\gamma^*+T\to \gamma^*+T$ scattering at large energies and the $k_t$factorization, and use it to evaluate the scales of the hard processes in thecurrent fragmentation region. We derive within the black disc (BD) regime themodified Gribov formula for the total cross-section of the DIS. We evaluate thecoherence length of the processes relevant for the BD regime and find that itincreases with energy as $\sim s^{0.6}$ i.e. significantly slower than in theparton model ($1/2m_Nx$ - the Ioffe length) as well as in pQCD. In the BDregime we estimate the gluon densities, local in the coordinate space, and findthat they do not decrease with the energy. We discuss briefly how the new pQCDphenomena may reveal itself in the proton-proton collisions at LHC
