Spectra and Elliptic Flow of (Multi)Strange Hadrons at RHIC and LHC within Viscous Hydrodynamics + Hadron Cascade Hybrid Model
Using the (2+1)-dimensional ultrarelativistic viscous hydrodynamics + hadron cascade, VISHNU, hybrid model, we study the pT-spectra and elliptic flow of Λ, Ξ, and Ω in Au + Au collisions at sNN = 200 GeV and in Pb + Pb collisions at sNN = 2.76 TeV.

| description | Using the (2+1)-dimensional ultrarelativistic viscous hydrodynamics + hadron cascade, VISHNU, hybrid model, we study the pT-spectra and elliptic flow of Λ, Ξ, and Ω in Au + Au collisions at sNN = 200 GeV and in Pb + Pb collisions at sNN = 2.76 TeV. Comparing our model results with the data measurements, we find that the VISHNU model gives good descriptions of the measurements of these strange and multistrange hadrons at several centrality classes at RHIC and LHC. Mass ordering of elliptic flow v2 among π, K, p, Λ, Ξ, and Ω are further investigated and discussed at the two collision systems. We find that, at both RHIC and LHC, v2 mass ordering among π, K, p, and Ω is fairly reproduced within the VISHNU hybrid model, and more improvements are needed to be implemented for well describing v2 mass ordering among p, Λ, and Ξ. |
