Resumen

Measurements of elliptic (v₂) and triangular (v₃) flow coefficients of π^±, K^±, p+p ¯ , KS0, and Λ+Λ ¯ obtained with the scalar product method in Xe-Xe collisions at sNN = 5.44 TeV are presented. The results are obtained in the rapidity range |y| < 0.5 and reported as a function of transverse momentum, p_T, for several collision centrality classes. The flow coefficients exhibit a particle mass dependence for p_T< 3 GeV/c, while a grouping according to particle type (i.e., meson and baryon) is found at intermediate transverse momenta (3 < p_T< 8 GeV/c). The magnitude of the baryon v₂ is larger than that of mesons up to p_T = 6 GeV/c. The centrality dependence of the shape evolution of the p_T-differential v₂ is studied for the various hadron species. The v₂ coefficients of π^±, K^±, and p+p ¯ are reproduced by MUSIC hydrodynamic calculations coupled to a hadronic cascade model (UrQMD) for p_T< 1 GeV/c. A comparison with v_n measurements in the corresponding centrality intervals in Pb-Pb collisions at sNN = 5.02 TeV yields an enhanced v₂ in central collisions and diminished value in semicentral collisions.
