【 摘 要 】

The Nuclotron-based Ion Collider facility (NICA) in Dubna, Russia is currently under construction at the Joint Institute for Nuclear Research (JINR). A Multi Purpose Detector (MPD) at NICA is designed to study properties of baryonic dense matter in the range of center of mass collision energy from 4 to 11 GeV. We present a performance study for anisotropic transverse flow measurement in Au+Au collisions using the UrQMD event generator and Geant4 simulation of the MPD response. The collision symmetry plane is estimated from event-by-event transverse energy distribution in Forward Hadron Calorimeters (FHCal's). Performance of the MPD for a measurement of the directed (v1) and elliptic (v2) flow of identified charged hadrons is evaluated based on comparison between reconstructed v1and v2values and the input one from the UrQMD model.
