Multiplicity Difference Factorial Moments Scaling Behavior for some Phase Variables.
L. F. Babichev and A. N. Khmialeuski

The multiplicity difference correlators between two well-separated bins in high-energy heavy-ion collisions are studied with the help of Monte-Carlo simulations. They are calculated for the case of secondary charged hadrons from Pb+Pb collisions at 500 to 1400 GeV per nucleon for different phase variables: pseudorapidity, azimuthal angle and transverse momentum. Numerical values of universal scaling exponent are calculated to study phase transition QGP hadrons. The modeling of phase transition with the help of Monte Carlo generator is discussed. The methods of parallel programming are been used to reduce the time of calculations.
Key words: heavy-ion collisions, quark-gluon plasma, particle production, Monte-Carlo simulation, multiplicity distribution, phase transition, Ginzburg-Landau model, universal scaling exponents, intermittency
