摘要：

在这些诉讼中，我们报告椭圆（$v_{2}$）和三角形奇异和多奇异强子如$K_{S}^{0}$，~ $Λ$的（$v_{3}$）流测量（$\barΛ$），~ $ϕ$，~ $Ξ^{-}$（$\barΞ^{+}$），关于$Ω^{-}$使用高统计束能量扫描第二阶段（BES-II）数据，在$\sqrt{s_{NN}}$ = 19.6 GeV的Au+Au碰撞中，计算了中等快度（$|y| < 1.0$）下的（$\barΩ^{+}$）。研究了这些粒子的横动量（$p_{T}$）依赖性、中心性依赖性和$v_{2}$和$v_{3}$的组分夸克数（NCQ）标度.与粒子相比，在反粒子的情况下观察到更好的NCQ标度，这可以归因于粒子中输运夸克的贡献。流体动力驱动比（$v_{3}/v_{2}^{3/2}$）是$p_{T}$的函数。

英文摘要：

In these proceedings, we report the elliptic ($v_{2}$) and triangular ($v_{3}$) flow measurements of strange and multi-strange hadrons such as $K_{S}^{0}$, ~$Λ$($\barΛ$), ~$ϕ$, ~$Ξ^{-}$($\barΞ^{+}$), and $Ω^{-}$($\barΩ^{+}$) at mid-rapidity ($|y| < 1.0$) in Au+Au collisions at $\sqrt{s_{NN}}$ = 19.6 GeV using high statistics Beam Energy Scan Phase-II (BES-II) data. The transverse momentum ($p_{T}$) dependence, centrality dependence, and the number of constituent quarks (NCQ) scaling of $v_{2}$ and $v_{3}$ are studied for all these particles. A better NCQ scaling is observed in the case of antiparticles compared to particles, which can be attributed to the contribution from the transported quarks in particles. The hydrodynamically motivated ratio ($v_{3}/v_{2}^{3/2}$) is presented as a function of $p_{T}$.
