The most stringent constraints currently available on the high-density EOS of symmetric nuclear matter come from the present measurements of directed (v(1)) and elliptic flow (v(2)) signals of protons in Au + Au collisions. In this energy range, the anisotropic flow is strongly affected by the presence of cold spectators due to the sizable passage time. The system size dependence of anisotropic flow may help to study the participant-spectator contribution and improve our knowledge of the EOS of symmetric nuclear matter. In this work, we discuss the layout of the upgraded BM@N experiment and the anticipated performance for differential anisotropic flow measurements of identified hadrons at Nuclotron energies: v???????s(NN)= 2.3-3.5 GeV.
- ПубликацияОткрытый доступCentrality Selection Effect on Elliptic Flow Measurements in Relativistic Heavy-Ion Collisions at NICA Energies(2023) Idrisov, D.; Parfenov, P.; Taranenko, A.; Идрисов, Дим Маратович; Парфенов, Петр Евгеньевич; Тараненко, Аркадий ВладимировичThe 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 v(s)NN = 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.
