dc.description.abstract | The elliptic (v2), triangular (v3), and quadrangular (v4) ow coe cients of , K , p + p, + , K0 S, and the -meson are measured in Pb-Pb collisions at p sNN = 5:02TeV. Results obtained with the scalar product method are reported for the rapidity range jyj < 0.5 as a function of transverse momentum, pT, at di erent collision centrality intervals between 0{70%, including ultra-central (0{1%) collisions for , K , and p + p. For pT < 3 GeV=c, the ow coe cients exhibit a particle mass dependence. At intermediate transverse momenta (3 < pT < 8{10 GeV=c), particles show an approximate grouping according to their type (i.e., mesons and baryons). The -meson v2, which tests both particle mass dependence and type scaling, follows p + p v2 at low pT and v2 at intermediate pT. The evolution of the shape of vn(pT) as a function of centrality and harmonic number n is studied for the various particle species. Flow coe cients of , K , and p + p for pT < 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 pT < 2:5 GeV=c, while MUSIC calculations reproduce the measurements for pT < 1 GeV=c. A comparison to vn coe cients measured in Pb-Pb collisions at p sNN = 2.76TeV is also provided. | en |
