Description
A two-dimensional intermittency analysis performed for the charged particles produced in ($\eta, \varphi$) phase space during Xe--Xe collisions at $\sqrt{s_{\rm{{NN}}}}$ = 5.44 TeV recorded with the ${\rm ALICE}$ detector at LHC is presented. A well-known characteristic of the critical behaviour of the system undergoing phase transition is that it shows fluctuations of all scales. Local multiplicity fluctuations are analyzed using normalized factorial moments (NFM) $F_{\rm{q}}$ for $q={\rm2,\,3,\,4\,and\,5}$. For the systems with dynamical fluctuations $F_{\rm{q}}$ shows scaling behaviour with increasing numbers of bins $M$ whereas scaling is also characteristic of the systems with self-similar and fractal nature. $F_{\rm{q}}$ moments show scaling behaviour as the binning in the phase space region increases.
For the second-order phase transition in the Ginzburg-Landau formalism $F_{\rm{q}}$ for $q > $ 2 shows a linear dependence on the second-order normalized factorial moments ($F_{\rm{2}}$), termed as F-scaling. The scaling exponent $\nu$, which quantifies the fluctuations in the particle density distributions, was determined for various $p_{\rm{T}}$ intervals and bin widths in the soft-$p_{\rm{T}}$ region. Observations and results from this study and comparison with Pb--Pb results at LHC energies will be discussed.
