Global Polarization of Λ Hyperons and Its Correlation with the Directed Flow at NICA Energies

Global hyperon polarization and anisotropic transverse flow are important observables for studying the properties of the strongly interacting matter produced in relativistic heavy ion collisions. The former provides information about the initial angular momentum in the non-central collisions and the latter contains information about the early evolution of the overlap region and the equation of state. Investigating of both effects at NICA energies is an important goal of the MPD experiment. In this work we study the global polarization of Λ hyperons and its correlation with the directed flow of the strongly interacting matter produced in the Bi + Bi collisions at $$\sqrt {{{s}_{{NN}}}} $$ = 9.2 GeV generated with the PHSD (Parton–Hadron–String Dynamics) model.
