Description
Saturation of gluon distribution is a consequence of
non-linear evolution equations of QCD. Saturation implies
the existence of so called saturation momentum which is
gluon density per unit rapidity per transverse area. At
large energies for certain kinematical domains saturation
momentum is the only scale for physical processes. As
a consequence different observables exhibit so called
geometrical scaling (GS). We shall discuss a number of
examples of GS and its violation in different reactions.
