Flow performance studies with MPD (NICA)

• Arkadiy Taranenko (NRNU MEPhI)

Room: 241 Performance studies of anisotropic flow with MPD at NICA The Multi-Purpose Detector (MPD) at NICA collider has a substantial discovery potential concerning the exploration of the QCD phase diagram in the region of high net-baryon densities and moderate temperatures. The anisotropic transverse flow is one of the key observables to study the properties of dense matter created in heavy-ion collisions. The MPD performance for anisotropic flow measurements is studied with Monte-Carlo simulations of gold ions at NICA energies $\sqrt {{S_{NN}}} = 4 - 11 GeV using different heavy-ion event generators. Different combinations of the MPD detector subsystems are used to investigate the possible systematic biases in flow measurements, and to study effects of detector azimuthal non-uniformity. The resulting performance of the MPD for flow measurements.

Centrality determination in heavy-ion collisions with the TPC(MPD)

• Peter Parfenov (MEPhI, Moscow)

Room: 241 Centrality Determination in Heavy-ion Collisions with MPD (NICA) Centrality is a key parameter for defining the collision system size in relativistic heavy-ion collisions. It provides a tool for selecting events according to cross section in a similar way in different experiments and with theoretical model calculations. The progress of centrality determination in Au+Au collisions using the multiplicity of charged tracks in TPC(MPD) will be presented and discussed.
