Sažetak
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 anti-particles 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.
