英文摘要	The elliptic (v(2)), triangular (v(3)), and quadrangular (v(4)) flow coefficients of pi(+/-), K-+/-, p + (p) over bar, Lambda + (Lambda) over bar, K-S(0)), and the phi-meson are measured in Pb-Pb collisions at root(NN)-N-s = 5.02 TeV. Results obtained with the scalar product method are reported for the rapidity range vertical bar y vertical bar < 0.5 as a function of transverse momentum, P-T, at different collision centrality intervals between 0-70%, including ultra-central (0-1%) collisions for pi(+/-), K-+/-, and p + (p) over bar. For P-T < 3 GeV/c, the flow coefficients exhibit a particle mass dependence. At intermediate transverse momenta (3 < p(T) < 8-10 GeV/c), particles show an approximate grouping according to their type (i.e., mesons and baryons). The phi-meson v(2), which tests both particle mass dependence and type scaling, follows p + <(p)over bar> v(2) at low P-T and pi(+/-) v(2) at intermediate p(T). The evolution of the shape of v(n) (p(T)) as a function of centrality and harmonic number n is studied for the various particle species. Flow coefficients of pi(+/-), K-+/- , and p + (p) over bar for p(T) < 3 GeV/c are compared to iEBE-VISHNU and MUSIC hydrodynamical calculations coupled to a hadronic cascade model (UrQMD). The iEBE-VISHNU calculations describe the results fairly well for P-T < 2.5 GeV/c, while MUSIC calculations reproduce the measurements for p(T) < 1 GeV/c. A comparison to vn coefficients measured in Pb-Pb collisions at root(NN)-N-s = 2.76 TeV is also provided.
