Description
In heavy-ion collisions, the spin polarization of Λ hyperon is an important measure to probe the vorticity of the quark-gluon plasma. On the other hand, other hyperons such as $Ξ^−$ and $Ω^−$ should also possess the global polarization similar to $Λ$.
In this talk, I will show our recent theoretical results on the global polarization of $Λ$, $Ξ^−$ and $Ω^−$ hyperons in non-central Au+Au collisions in the energy range 7.7−200 GeV. The effect of resonance decays on the global polarization of $Λ$ and $Ξ^−$ is also investigated. Our results provide a quantitative relation between the global polarization of $Λ$, $Ξ^−$ and $Ω^−$ hyperons. This provides us a means to further test the vorticity interpretation of the global polarization in experiments.
