Description
Using a (3+1)D hydrodynamic model, we analyze Λ hyperon polarization in heavy-ion collisions at √sNN = 200 GeV, revealing a strong dependence on initial conditions and QGP viscosity. The model accurately reproduces hadronic flow observables and predicts higher-order azimuthal oscillations in longitudinal polarization. Novel correlations between polarization and anisotropic flow are proposed, offering new experimental tests. A system-size study confirms a dependence consistent with vorticity, providing crucial constraints on quark-gluon plasma dynamics and spin-polarization mechanisms.
