The elliptic flow ( v 2 ) of produced particles is one of the important observables sensitive to the transport properties of the strongly interacting matter created in relativistic heavy-ion collisions. Detailed differential measurements of v 2 are also foreseen in the future Multi-Purpose Detector (MPD) experiment at the Nuclotron based Ion Collider fAcility (NICA) at collision energies s N N = 4–11 GeV. Elliptic flow strongly depends on collision geometry, defined by the impact parameter b. Usually b is an input to theoretical calculations and can be deduced from experimental observables in the final state using the centrality procedure. In this work, we investigate the influence of the choice of centrality procedure on the elliptic flow measurements at NICA energies. [ABSTRACT FROM AUTHOR]

The elliptic flow v 2 is one of the key observables sensitive to the transport properties of the strongly interacting matter formed in relativistic heavy-ion collisions. In this work, we report on the calculations of v 2 and its fluctuations of charged hadrons produced in Au+Au collisions at center-of-mass energy per nucleon pair s N N = 7.7 and 11.5 GeV from several transport models and provide a direct comparison with published results from the STAR experiment. This study motivates further experimental investigations of v 2 and its fluctuations with the Multi-Purpose Detector (MPD) at the NICA Collider. [ABSTRACT FROM AUTHOR]
