Recently, the STAR collaboration has measured the Λ and Λ polarizations as functions of the transverse momentum and the pseudorapidity in 200 GeV Au-Au collisions at RHIC. In this study, the global polarization has been measured, and the results presents some differences when comparedwith the ones obtained in proton-nucleus collisions. These results can be understood in terms of a model that we recently proposed, that is based on the hydrodynamical model, and taking into account the average effect of the final-state interactions (that occur in the hadronic phase) between the hyperons and other produced particles. In this work, we show how this model may be applied in such collisions, and also will discuss the relation of our results with other models, in order to explain the experimental data.
