Elliptic flow of charged and strange hadrons in PbAu collisions at 158 AGeV/c measured in CERES experiment
Differential elliptic flow of υ2(pT) for π−, Ks0, p and Λ is measured at centerof-mass energy of √sNN=17.3 GeV near the mid-rapidity region in rather central PbAu collisions collected by the CERES/NA45 experiment at CERN. The proton υ2(pT) is extracted from π+ sample and particle ratios measured by...

| description | Differential elliptic flow of υ2(pT) for π−, Ks0, p and Λ is measured at centerof-mass energy of √sNN=17.3 GeV near the mid-rapidity region in rather central PbAu collisions collected by the CERES/NA45 experiment at CERN. The proton υ2(pT) is extracted from π+ sample and particle ratios measured by NA49 experiment adapted to CERES conditions. The proton υ2(pT) data show a downward swing towards low pT with excursions into negative υ2 values which was not observed earlier. The results are compared with corresponding measurements performed at NA49 and STAR experiments as well as with theoretical predictions from ideal relativistic hydrodynamics. The obtained results for baryons are below hydrodynamic predictions even at the kinetic freeze-out temperature of Tf=160 MeV which needs introducing of a viscous hydrodynamics at the late hadronic phase. |
