Description
The study of global polarization in heavy-ion collisions has revealed the presence of a vortical fluid with significant angular momentum and vorticity. This phenomenon can be observed through weak decays of particles such $\Lambda$ hyperons. Experimental data of $\Lambda$ global polarization from RHIC and LHC provided
opportunity to get new insights into the collective behavior and hydrodynamic description of
the system.
Global polarization of multistrange hyperons, such as $\Xi$, can provide new information for hydrodynamic description of the system and its vorticity structure. In this talk, we will report results of $\Xi$ global polarization measurement for Au+Au collisions at $\sqrt{s_{NN}}$ = 19.6 and 27 GeV.
