Global polarization in moderately relativistic nuclear collisions
Abstract
Predictions for the global polarization of hyperons in Au+Au collisions at moderately relativistic collision energies, 2.4 ≤sNN≤ 11 GeV, are made. These are based on the thermodynamic approach to the global polarization incorporated into the model of the three-fluid dynamics. Centrality dependence of the polarization is studied. It is predicted that the polarization reaches a maximum or a plateau (depending on the equation of state and centrality) at sNN≈ 3 GeV. It is found that the global polarization increases with increasing width of the rapidity window around the midrapidity.
