The self-consistent approach based on similarity of inclusive spectra of
hadrons produced in pp and AA collisions is reviewed. This approach allows
us to describe rather well the ratio of proton to anti-proton yields in AA
collisions as a function of the initial energy at a wide range from a few GeV
to a few TeV. We suggest its modification due to the quark-gluon dynamics to
describe the inclusive spectra of hadrons produced in pp collision as a
function of the transverse momentum pt at mid-rapidity. The extension of
this approach to analyze the pion pt-spectra produced in AA collision at
high and middle energies and mid-rapidity is given. The satisfactory
description of experimental data on these spectra in pp and AA collisions
within the offered approach is shown.Comment: 15 pages, 9 figures. arXiv admin note: substantial text overlap with
