Description of First-order QGPHadron Phase Transition within generalized Ginzburg-Landau model in Heavy-Ion Collisions.
L.F. Babichev, V.I. Kuvshinov and V.A. Shaparau

We use the generalized Ginzburg-Landau theory for description both first and second order quark-hadron phase transition in quark-gluon plasma. In the framework of this theory the intermittency and scaling are investigated by different multiplicity distributions. It is shown that the normalized factorial moments exhibit a specific behaviour as functions of the resolution scale.
Key words: Ginzburg-Landau theory, phase transition, coherent state, factorial moment, multiplicity distribution, intermittency, scaling exponent
