Abstract

Quark-hadron phase transition is simulated by an event generator that incorporates the dynamical properties of contraction due to QCD confinement forces and randomization due to the thermal behavior of a large quark system on the edge of hadronization. Fluctuations of emitted pions in the (η,ϕ)(\eta,\phi) space are analyzed using normalized factorial moments in a wide range of bin sizes. The scaling index ν\nu is found to be very close to the predicted value in the Ginzburg-Landau formalism. The erraticity indices μq\mu_q are determined in a number of ways that lead to the same consistent values. They are compared to the values from the Ising model, showing significant difference in a transparent plot. Experimental determination of ν\nu and μq\mu_q at the LHC are now needed to check the reality of the theoretical study and to provide guidance for improving the model description of quark-hadron phase transition.
