Spectra and Elliptic Flow of (Multi)Strange Hadrons at RHIC and LHC within Viscous Hydrodynamics + Hadron Cascade Hybrid Model

Figure 1

Transverse momentum spectra of (), (), and at various centralities in Au + Au collisions at = 200 GeV. Experimental data are taken from STAR measurements [15]. Theoretical curves are calculated by the VISHNU hybrid model with the parameters presented in Section 2. From top to bottom the curves correspond to 0–5% (), 10–20% (), 20–40% (), 40–60% (), and 60–80% () centrality, respectively, where the factors in parentheses are the multipliers applied to the spectra for clear separation. The multiplied factor for spectra of at 20–40% is instead of . In VISHNU, the spectra of particles and corresponding antiparticles are the same due to zero net-baryon density used in our calculations. Therefore, only results of particles are shown with solid curves.
