论文摘要
在这些程序中，我们报告了椭圆形（$ v_ {2} $）和三角形（$ v_ {3} $）流量测量奇怪和多矛盾的哈子，例如$ k_ {s}^{0}^{0} $，〜$λ$（$ \barλ$），在$ \ sqrt {$ | y | <1.0 $）上的$ \ | y | <1.0 $）在$ \ sqrt {$ | y | <1.0 $）上进行$ \ \ y | <1.0 $ collisions $ \ sqrt {s_ {nn}} $ = 19.6 GEV使用高统计型梁射击射击beam Energy SCAN阶段 - II（BES -III）数据。对于所有这些粒子，研究了横向动量（$ p_ {t} $）依赖性，中心性依赖性以及$ v_ {2} $和$ v_ {3} $的组成夸克（NCQ）缩放的数量。与颗粒相比，在反颗粒的情况下，观察到更好的NCQ缩放率，这可以归因于颗粒中运输的夸克的贡献。流体动力动机比率（$ v_ {3}/v_ {2}^{3/2} $）作为$ p_ {t} $的函数。
In these proceedings, we report the elliptic ($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 $p_{T}$.
