Abstract
The polarization of hyperons due to axial chiral vortical effect is discussed. The effect is proportional to chemical potential squared and is pronounced at lower energies in baryon-rich matter. The polarization of antihyperons has the same sign and larger magnitude. The emergence of vortical structures is observed in kinetic QGSM models. The hydrodynamical helicity separation receives the contribution of longitudinal velocity and vorticity implying the quadrupole structure of the latter. The transition from the quark vortical effects to baryons in confined phase may be achieved by exploring the axial charge.
