Event anisotropy<i>v</i>₂of identified hadrons and light nuclei in Au+Au collisions at \sqrt{s_{{\rm NN}}} = 7.7, 11.5 and 39 GeV with STAR

We present v2 measurements from Au+Au collisions at = 7.7, 11.5 and 39 GeV for identified hadrons (?, K, K0s, p, , ?, ?) and light nuclei ( and 3He). For the first time, a significant difference in v2 between baryons and anti-baryons is observed. The difference increases with decreasing center-of-mass energy. A systematically lower -meson v2, compared to the other particles, is observed in the frame of the number-of-constituent quark scaling.
