Probe the QCD phase boundary with elliptic flow in relativistic heavy ion collisions at STAR
We present measurement of elliptic flow, , for charged and identified
particles at midrapidity in Au+Au collisions at = 7.7 - 39 GeV.
We compare the inclusive charged hadron to those from transport model
calculations, such as UrQMD model, AMPT default model and AMPT string-melting
model. We discuss the energy dependence of the difference in between
particles and anti-particles. The of meson is observed to be
systematically lower than other particles in Au+Au collisions at
= 11.5 GeV.Comment: 5 pages, 3 figures, the proceedings of the 7th International Workshop

STAR Highlights on Heavy Ion Physics
RHIC-STAR is a mid-rapidity collider experiment for studying high energy
nuclear collisions. The main physics goals of STAR experiment are 1) studying
the properties of the strongly coupled Quark Gluon Plasma, 2) explore the QCD
phase diagram structure. In these proceedings, we will review the recent
results of heavy ion physics at STAR.Comment: 8 pages, 8 figures. The proceedings of ICNFP201
