Abstract

Measurements of elliptic (v<inf>2</inf>) and triangular (v<inf>3</inf>) flow coefficients of π<sup>±</sup>, K<sup>±</sup>, 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<inf>T</inf>, for several collision centrality classes. The flow coefficients exhibit a particle mass dependence for p<inf>T</inf>< 3 GeV/c, while a grouping according to particle type (i.e., meson and baryon) is found at intermediate transverse momenta (3 < p<inf>T</inf>< 8 GeV/c). The magnitude of the baryon v<inf>2</inf> is larger than that of mesons up to p<inf>T</inf> = 6 GeV/c. The centrality dependence of the shape evolution of the p<inf>T</inf>-differential v<inf>2</inf> is studied for the various hadron species. The v<inf>2</inf> coefficients of π<sup>±</sup>, K<sup>±</sup>, and p+p ¯ are reproduced by MUSIC hydrodynamic calculations coupled to a hadronic cascade model (UrQMD) for p<inf>T</inf>< 1 GeV/c. A comparison with v<inf>n</inf> measurements in the corresponding centrality intervals in Pb-Pb collisions at sNN = 5.02 TeV yields an enhanced v<inf>2</inf> in central collisions and diminished value in semicentral collisions.
