摘要：
We present triangular flow (v(3)) measured by STAR for identified particles (pi(+/-), K-+/-, p, (p) over bar and phi) relative to the third-harmonic event plane as a function of p(T) for minimum bias (0%-80%) Au + Au collisions at root S-NN = 39 GeV and 200 GeV. We discuss the hydrodynamic description of the mass ordering at low p(T) (p(T) < 1.5 GeV/c), number-of-constituent-quark (NCQ) scaling at intermediate p(T) (0.5 GeV/c < p(T)/n(q) < 1.5 GeV/c), and the ratio of v(2)/v(3) at the p(T) of the crossing of the identified particle v3.
