论文摘要
轻核和超核在重离子碰撞中产生。这些物种在重离子碰撞中的生产机制还有待理解。在这些程序中，我们报告了椭圆流（$ v_2 $）的横向动量和中心性依赖性为$ d $，$ t $和$^3 \ 3 \ text {he} $ in Au+au collisions in $ \ sqrt {s_ {s_ {nn}} $ = 14.6、19.6、19.6、29.6、27、27、27、27、27、27、27、27、27、27和54.4 g。显示了$ v_2（p_t）$的质量缩放光核。我们还报告了Hyper-Nuclei $^{3}_λ$ H和$^{4}_λ$ H定向流（$ v_1 $）中的第一个观察结果。
Light nuclei and hyper-nuclei are produced in abundance in heavy-ion collisions. The production mechanism of these species in heavy-ion collisions still remains to be understood. In these proceedings, we report the transverse momentum and centrality dependence of elliptic flow ($v_2$) of $d$, $t$, and $^3\text{He}$ in Au+Au collisions at $\sqrt{s_{NN}}$ = 14.6, 19.6, 27, and 54.4 GeV. Mass number scaling of $v_2(p_T)$ of light nuclei is shown. We also report the first observation of hyper-nuclei $^{3}_Λ$H and $^{4}_Λ$H directed flow ($v_1$) in $\sqrt{s_{NN}}$ = 3 GeV mid-central (5-40\%) Au+Au collisions in the fixed target mode.
