Query: Axial anomaly and energy dependence of hyperon polarization in Heavy-Ion
  Collisions   We address the issue of energy and charge dependence of global polarization
of $\Lambda$ hyperons in peripheral $Au-Au$ collisions recently observed by the
STAR collaboration at RHIC. We compare different contributions to the anomalous
mechanism relating polarization to vorticity and hydrodynamic helicity in QCD
matter. We stress that the suppression of the gravitational anomaly
contribution in strongly correlated matter observed in lattice simulations
confirms our earlier prediction of rapid decrease of polarization with
increasing collision energy. Our mechanism leads to polarization of $\bar
\Lambda$ of the same sign and larger magnitude than the polarization of
$\Lambda$. The energy and charge dependence of polarization is suggested as a
sensitive probe of fine details of QCD matter structure.
