Abstract

Abstract : In this paper, by using a Tsallis-Pareto-type function and the multisource thermal model, the elliptic flow coefficients of particles π ±, K ±, p + p ¯, Λ + Λ ¯, and K S 0 produced in Pb–Pb collisions at the center-of-mass energy of s NN = 5.02 T e V are investigated. In the process of collisional evolution, because of geometric structure, pressure gradient, and thermal diffusion effects, deformation and translation occurred in the isotropic emission source, leading to anisotropy in the azimuth distribution of the final-state particles. Based on these dynamic factors, the dependence of elliptic flow on transverse momentum is described as well.
