The role of axial anomaly in the generation of hyperons polarisation is discussed. The appearance of vorticit6y as gauge field strength and
chemical potential as a coupling constant provide the robust exlanation of the energy dependence of polarisation related to induced quark axial current.
The transition from quarks to hadrons is controlled by quark-hadfron duality, quantified in terms of axial charge or quantized vortices in pionic superfluid.
The polarisation of antibaryons is expected to be of the same size and larger magnitude than that of baryons. The interplay with the thermodynamoc approach to polarisation is studied by calculating the induced axial current in Wigner function approach and is attributed to depndence on fermion mass.
