Description
Quantum Chromodynamics (QCD) predicts a transition form hadronic matter to a deconfined state of quarks and gluons known as quark gluon plasma (QGP) under extreme conditions of temperature and/or baryon chemical potential ($\mu_B$). One of the main objectives of the relativistic heavy-ion collision experiments is to explore the properties of strongly interacting QGP. Azimuthal anisotropy of the final-state hadrons has been studied intensively to look for the dynamics and collecitve behavior of the strongly interacting medium produced in relativistic heavy-ion collisions. Elliptic flow ($v_{2}$) of identified hadrons provides a strong evidence for the creation of a hot and dense matter in heavy-ion collisions. The most striking observation, in this respect, is the number of constituent quark (NCQ) scaling of $v_{2}$ of identified hadrons.
In this work, we report the transverse momentum ($p_T$) dependence of identified hadron $v_{2}$ at mid-rapidity ($|y| < 1.0$) in minimum bias Au+Au collisions at $E_{lab} = 25\mathrm{~A~GeV}$ and $35\mathrm{~A~GeV}$ using the Parton Hadron String Dynamics (PHSD) model. The number of constituent quark (NCQ) scaling of $v_2$ will be discussed. We will also discuss the $v_2(p_T)$ difference between particles and corresponding anti-particles. The calculations are compared with the published results from the STAR experiment at RHIC for Au+Au collisions at $\sqrt{s_{\mathrm{NN}}} = 7.7\mathrm{~GeV}$. These predictions will 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).
