We present systematic measurements of azimuthal anisotropy for strange and multistrange hadrons ($K_s^0, \mathrm{\Lambda }, \mathrm{\Xi }$, and $\mathrm{\Omega }$) and $\varphi$ mesons at midrapidity ($\left|y\right|<$ 1.0) in collisions of $\mathrm{U}+\mathrm{U}$ nuclei at $\sqrt{s_{NN}}=193$ GeV, recorded by the STAR detector at the Relativistic Heavy Ion Collider. Transverse momentum ($p_T$) dependence of flow coefficients ($v_2, v_3$, and $v_4$) is presented for minimum bias collisions and three different centrality intervals. Number of constituent quark scaling of the measured flow coefficients in $\mathrm{U}+\mathrm{U}$ collisions is discussed. We also present the ratio of $v_n$ scaled by the participant eccentricity (${\varepsilon }_n\left\{2\right\}$) to explore system size dependence and collectivity in $\mathrm{U}+\mathrm{U}$ collisions. The magnitude of $v_2/{\varepsilon }_2$ is found to be smaller in $\mathrm{U}+\mathrm{U}$ collisions than that in central $\mathrm{Au}+\mathrm{Au}$ collisions contradicting naive eccentricity scaling. Furthermore, the ratios between various flow harmonics ($v_3/v_2^{3/2}, v_4/v_2^{4/2}$) are studied and compared with hydrodynamic and transport model calculations.

在 BNL 相对论重离子对撞机上在 sNN=193GeV 的 U+Ucollisions atsNN=193GeV 中奇异和多奇异强子的方位角各向异性测量

我们提出了奇异和多奇异强子的方位角各向异性的系统测量（${钾}_{秒}^0, \mathrm{\Lambda }, \mathrm{\Xi }$， 和 $\mathrm{\Omega }$） 和 $\phi$ 中速介子 ($\left|是\right|<$ 1.0) 在碰撞中 $\mathrm{你}+\mathrm{你}$ 核在 $\sqrt{{秒}_{NN}}=193$GeV，由相对论重离子对撞机的 STAR 探测器记录。横向动量 (${磷}_{吨}$) 流量系数的相关性 ($v_2, v_3$， 和 $v_4$) 用于最小偏差碰撞和三个不同的中心性区间。测得的流动系数的成分夸克标度数$\mathrm{你}+\mathrm{你}$碰撞进行了讨论。我们还提供了$v_n$ 由参与者的离心率（${\varepsilon }_n\left\{2\right\}$) 探索系统规模依赖性和集体性 $\mathrm{你}+\mathrm{你}$碰撞。的大小$v_2/{\varepsilon }_2$ 被发现较小 $\mathrm{你}+\mathrm{你}$ 碰撞比在中心 $金+金$碰撞与朴素的离心率缩放相矛盾。此外，各种流量谐波之间的比率（$v_3/v_2^{3/2}, v_4/v_2^{4/2}$) 进行了研究，并与水动力和输运模型计算进行了比较。
