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

Figure 2

Transverse momentum spectra of , (), and () at various centralities in Pb + Pb collisions at = 2.76 TeV. Experimental data are taken from LHC [21, 22]. Theoretical curves are calculated with the VISHNU hybrid model with the parameters presented in Section 2. From top to bottom the curves correspond to 0–10% (), 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. Spectra of start from 0–5% () and 5–10% (), instead of 0–10%. In VISHNU, the spectra of particles and corresponding antiparticles are same due to zero net-baryon density used in our calculations. Therefore, only results of particles are shown with solid curves.
