Observation of an Energy-Dependent Difference in Elliptic Flow between Particles and Antiparticles in Relativistic Heavy Ion Collisions
Elliptic flow (v[subscript 2]) values for identified particles at midrapidity in Au+Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at √s[subscript NN]=7.7–62.4 GeV, are presented. A beam-energy-dependent difference of the values of v[subscript 2] between particles an...
