- Abstract: Elliptic flow (v2) values for identified particles at mid-rapidity in Au+Au collisions, measured by the STAR experiment in the Beam Energy Scan at RHIC at √ sNN = 7.7–62.4 GeV, are presented. A beam-energy dependent difference of the values of v2 between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and anti-particles are not consistent with the universal number-of-constituent-quark (NCQ) scaling of v2 that was observed at √ sNN = 200 GeV.
