Analysis Note: Directed flow $v_1$ of protons in the Xe+Cs(I) collisions at 3.8 AGeV

In this note, we present the directed flow $v_1$ measurements of protons from Xe+Cs(I) collisions at 3.8 AGeV (BM@N run8). We show the datasets, event and track selection cuts, centrality definition, event plane reconstruction and resolution. The $v_1$ results are presented as function of transverse momentum ($p_T$) and rapidity ($y_{cm}$) for 10-30\% central Xe+Cs(I) collisions. The systematic uncertainty study will also be presented and discussed. The $v_1$ measurements are compared with results of JAM transport model calculations and published data from other experiments.

Comparison of Methods for Elliptic Flow Measurements at NICA Energies $\sqrt{s_{NN}}$ = 4-11 GeV

The goal of the Multi-Purpose Detector (MPD) experiment at NICA collider is to explore the QCD phase diagram of strongly interacting matter produced in nucleus-nucleus collisions at $\sqrt{s_{NN}}=4-11$ GeV. The performance of MPD detector for elliptic flow measurements of charged hadrons is studied with Monte-Carlo simulations using collisions of Au+Au ions employing UrQMD, SMASH, and AMPT heavy-ion event generators. Different methods for flow measurements: event plane and direct cumulants are used to investigate the contribution of non-flow correlations and flow fluctuations.
