“…In both cases, the particles detected in the TPC of the STAR experiment (|η| < 1.0) have been used. In this section, we briefly discuss how the event plane and Q-cumulant methods can be used for the measurements of elliptic flow of the produced particles with an MPD detector system at NICA [31]. Similar to the STAR experiment, the particles detected in the TPC (|η| < 1.5) of the MPD experiment have been used.…”

Centrality Selection Effect on Elliptic Flow Measurements in Relativistic Heavy-Ion Collisions at NICA Energies

The elliptic flow (v2) 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 v2 are also foreseen in the future Multi-Purpose Detector (MPD) experiment at the Nuclotron based Ion Collider fAcility (NICA) at collision energies sNN = 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.

“…(left), two-particle cumulants v 2 {2} (middle) and TPC event plane v 2 {Ψ 2,TPC } (right). The agreement between v 2 (p T derived from a fully reconstructed data analysis based on GEANT4 (open symbols) and UrQMD model data (filled symbols) indicate good performance of the MPD for the detailed differential measurements of v 2[31,33].…”
