论文摘要

Elliptic ($v_2$) and triangular ($v_3$) anisotropic flow coefficients for inclusive and identified charged hadrons (~$π^\pm$, $K^\pm$, $p$, $\bar{p}$~) at midrapidity in Au+Au collisions, measured by the STAR experiment in the Beam Energy Scan (BES) at the Relativistic Heavy Ion出现了$ \ sqrt {s_ {nn}} $ = $ 11.5 $ - $ 62.4 $ GEV的对撞机。 We observe that the triangular flow signal ($v_3$) of identified hadrons exhibits similar trends as first observed for $v_2$ in Au+Au collisions, i.e. (i) mass ordering at low transverse momenta, $p_T < 2$ GeV/c, (ii) meson/baryon splitting at intermediate $p_T$, $2< p_T < 4$ GeV/c, and (iii) difference在质子和抗树脂子的流动信号中。 $ v_3 $激发功能的新测量可以作为测试不同模型的约束,并帮助有关强度相互作用物质的传输属性温度依赖性的新信息。

Elliptic ($v_2$) and triangular ($v_3$) anisotropic flow coefficients for inclusive and identified charged hadrons (~$π^\pm$, $K^\pm$, $p$, $\bar{p}$~) at midrapidity in Au+Au collisions, measured by the STAR experiment in the Beam Energy Scan (BES) at the Relativistic Heavy Ion Collider at $\sqrt{s_{NN}}$ = $11.5$ - $62.4$ GeV, are presented. We observe that the triangular flow signal ($v_3$) of identified hadrons exhibits similar trends as first observed for $v_2$ in Au+Au collisions, i.e. (i) mass ordering at low transverse momenta, $p_T < 2$ GeV/c, (ii) meson/baryon splitting at intermediate $p_T$, $2< p_T < 4$ GeV/c, and (iii) difference in flow signal of protons and antiprotons. New measurements of $v_3$ excitation function could serve as constraints to test different models and to aid new information about the temperature dependence of the transport properties of the strongly interacting matter.
