Abstrakt: Measurements of elliptic (v(2)) and triangular (v(3)) flow coefficients of pi(+/-), K-+/-, p+(p) over bar, K-S(0), and Lambda+(Lambda) over bar obtained with the scalar product method in Xe-Xe collisions at root sNN = 5.44TeV 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 pT < 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 v(2) is larger than that of mesons up to pT = 6 GeV/c. The centrality dependence of the shape evolution of the p(T)-differential v(2) is studied for the various hadron species. The v(2) coefficients of pi(+/-), K-+/-, and p+(p) over bar are reproduced by MUSIC hydrodynamic calculations coupled to a hadronic cascade model (UrQMD) for p(T) < 1 GeV/c. A comparison with vn measurements in the corresponding centrality intervals in Pb-Pb collisions at root sNN = 5.02TeV yields an enhanced v(2) in central collisions and diminished value in semicentral collisions.
