We investigate the nuclear modification factor (R AA ) of identified particles as a function of transverse momentum (p T ) in Pb-Pb collisions at √ s NN = 2.76 and 5.02 TeV, as well as p-Pb collision at 5.02 TeV in the framework of Boltzmann transport equation with relaxation time approximation. In this framework, the initial distribution of particles is chosen as the Tsallis distribution and the local equilibrium distribution as the Boltzmann-Gibbs blast-wave distribution. The nonextensive parameter q pp , the Tsallis temperature T pp and the equilibrium temperature T eq are set to be in common for all particles, while the ratio of kinetic freeze-out time to relaxation time t f /τ is different for different particles when we performed a combined fit to the R AA spectra of different particles at a given centrality. We observe that the fitted curves describe the spectra well up to p T ≈ 3 GeV/c. q pp and T eq (t f /τ ) decrease (increases) with centrality nonlinearly, while T pp is almost independent of centrality. The dependence of the rate at which q pp , T eq or t f /τ changes with centrality on the energy and the size of the colliding system is discussed.

The relaxation time approximation (RTA) is a well known method of describing the time evolution of a statistical ensemble by linking distributions of the variables of interest at different stages of their temporal evolution. We show that if all the distributions occurring in the RTA have the same functional form of a quasi-power Tsallis distribution the time evolution of which depends on the time evolution of its control parameter, nonextensivity q(t), then it is more convenient to consider only the time evolution of this control parameter.

In this work the transverse momentum spectra and nuclear modification factor for heavy ion collisions are derived using Tsalllis non-extensive statistics in relaxation time approximation. The Boltzmann-Gibbs Blast Wave (BGBW) function is used as the equilibrium function and Tsallis function is used as the initial distribution function while solving the Boltzmann transport equation in the relaxation time approximation. The framework is used to analyse the experimental data for particles like pions, kaons, protons, D 0 meson and J/Ψ produced in Pb+Pb collisions at s NN = 5.02 TeV at the LHC, CERN. We find that our proposed equation of state describes the experimental data successfully.
