Spectra and elliptic flow for $\Lambda$, $\Xi$, and $\Omega$ in 200 A GeV Au+Au collisions

Abstract

Using VISHNU hybrid model, we calculate the $p_{\rm T}$-spectra and elliptic flow of $\Lambda$, $\Xi$, and $\Omega$ in 200 A GeV Au+Au collisions. Comparisons with the STAR measurements show that the model generally describes these soft hadron data. We also briefly study and discuss the mass ordering of elliptic flow among $\pi$, $K$, $p$, $\Lambda$, $\Xi$, and $\Omega$ in minimum bias Au+Au collisions.
