Intermittency Study of Charged Particles Generated in Pb-Pb Collisions at Using EPOS3

Charged particle multiplicity fluctuations in Pb-Pb collisions are studied for the central events generated using EPOS3 (hydro and hydro+cascade) at . Intermittency analysis is performed in the midrapidity region in two-dimensional ( , ) phase space within the narrow transverse momentum ( ) bins in the low region ( ). Power-law scaling of the normalized factorial moments with the number of bins is not observed to be significant in any of the bins. Scaling exponent , deduced for a few bins, is greater than that of the value 1.304, predicted for the second-order phase transition by the Ginzburg-Landau theory. The link in the notions of fractality is also studied. Generalized fractal dimensions, , are observed to decrease with the order of the moment suggesting the multifractal nature of the particle generation in EPOS3
