  At sufficiently small $x$ where pQCD methods become insufficient we rewrote
sum of dominant Feynman diagrams for single-scale hard processes in the form of
the effective field theory where a quasiparticle corresponds to pQCD ladder. We
explain that pQCD series are divergent at small $x$ since pQCD produces tachyon
in effective field theory and because of degeneracy of vacua . Within the WKB
approximation we found the hierarchy among quasiparticle interactions due to
smallness of the QCD coupling constant which justifies restriction by the
triple quasiparticle interaction in the Lagrangean of effective field theory.
  Degeneracy of vacua is removed by accounting for the classical solutions
-kinks which cannot be decomposed into series over powers f $\alpha_s$ but
describe color inflation, Bose-Einstein condensation of quasiparticles. Quantum
fluctuations around the WKB solution lead to the spontaneous violation of
two-dimensional translation symmetry and the appearance of zero modes-
``phonons'' which are relevant for the black disc behaviour of small x
processes. Account of gluon exchanges between overlapping ladders neglected in
the first approximation produces a color network occupying a "macroscopic"
longitudinal volume. We discuss briefly possible role of new
  QCD phenomena in the two-scale hard processes .
