Intermittency study of charged particles generated in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}\text{= 2.76 TeV}$ using EPOS3

Charged particle multiplicity fluctuations in Pb-Pb collisions are studied for the central events generated using EPOS3 (hydro and hydro+cascade) at $\sqrt{s_{\mathrm{NN}}}\text{ = 2.76 TeV}$. Intermittency analysis is performed in the mid-rapidity region in two-dimensional ($\eta$, $\phi$) phase space within the narrow transverse momentum (p_\rm{{T}}) bins in the low p_\rm{{T}}~region (p_\rm{{T}}~\leq~1.0~GeV/\textit{c}). Power-law scaling of the normalized factorial moments with the number of bins is not observed to be significant in any of the p_\rm{{T}}-bin. Scaling exponent $\nu$, deduced for a few p_\rm{{T}} 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. Fractal dimensions, $D_{q}$ are observed to decrease with the order of the moment $q$ suggesting the multifractal nature of the particle generation in EPOS3.
