Following the quark-hadron duality concept, we show that the number of hadrons generated in the deconfinement matter is entirely determined by the exact non-equilibrium Green's functions of partons in the medium and the vertex function governing the probability of the confinement-deconfinement phase transition. In such an approach, compactifying the standard (3+1) chromodynamics into $ QCD_{xy} + QCD_{zt}$, the rate of the hadrons produced in particle collisions is derived in the explicit form provided that the hadronization is the first order phase transition. The pion production is found to be in good agreement to the experimental results on the pion yield in pp collisions.

Author comments upon resubmission

Dear Editors,
The author thanks the referee for remarks and criticism.
I hope that such a revised version will be accepted to be published in Proceedings.

Sincerely , Andrew Koshelkin.

List of changes

1. Following the referee remarks the author has added both equations and text to eliminate the gap between Eqs.(5) and (6) in the previous version (see the formulas and text from Eq.(6) to (10)).
2.The sum with respect to "a" as well as arising the symmetric Gaussian functions is explained just below Eq.(11).
3. After the same equation the author has commented the values of the parameters \sigma and y.
4. Figures gave been numbered.
5. The applicability of the obtained result to pA and AA collisions is discussed in Conclusion.
