Description
Global polarization of $\Lambda$ hyperons appearing in non-central heavy-ion collisions was measured by the STAR experiment at RHIC for Au+Au collisions with $\sqrt{s_{NN}}$ = 3-200 GeV and at the LHC for Pb+Pb collisions with $\sqrt{s_{NN}}$ = 2.76 and 5.02 TeV. Global polarization reflects the vortical structure of quark-gluon matter at its initial evolution stage.
Global polarization of multistrange hyperons, such as $\Xi$, can provide new information for hydrodynamic description of the system and its vorticity nature. In this talk, we will report results of $\Xi$ and $\Lambda$ global polarization measurement for Au+Au collisions at $\sqrt{s_{NN}}$ = 19.6, 27, and 54.4 GeV.
