We present predictions of elliptic flow (v 2) of identified hadrons at mid-rapidity (| y | < 1.0) in Au+Au collisions at E lab = 35 A GeV using the Parton Hadron String Dynamics (PHSD) model. The transverse momentum ( p T ) dependence of identified hadron v 2 in minimum bias (0–80%) and three different centrality intervals (0–10%, 10–40%, and 40–80%) are presented. A clear centrality dependence of v 2 (p T) is observed for particles and anti-particles. We also present the p T dependence of v 2 difference (Δ v 2) between particles and corresponding anti-particles. A significant difference in v 2 values for baryons and anti-baryons is observed. Constituent quark scaling (NCQ) of v 2 is investigated in Au+Au collisions. We also present a v 2 (p T) ratio between the HSD and PHSD modes to explore the effect of hadronic and partonic interactions in the medium. These predictions are useful for interpreting the data measured in the Beam Energy Scan (BES) program at RHIC. They will also be useful for the future Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) and Multi-Purpose Detector (MPD) at the Nuclotron-based Ion Collider facility (NICA).
