论文摘要
我们报告$ k_ {s}^{0} $，$λ$，$λ$，$ \barλ$，$ v_ {2} $，$ v_ {2} $，$ \barλ$，$ ϕ $，$ξ^{ - } $，$ \ overline了ξ^{+} $ in Mid-Rapity for Ru+Ru+ru+ru+zr collions $ ru+zr clusions $ sqr { {nn}}} $ = 200 GEV。已经研究了横向动量（$ p_ {t} $）和$ v_ {2} $的中心性依赖性。也测试了所有（多）奇怪的黑龙的组成夸克（NCQ）缩放数量。平均$ v_ {2} $（$ \ langle $$ v_ {2} $$ \ rangle $）的依赖性在中心度上显示出与统一的偏差，这表明核结构和等距之间的变形差异。与Cu+Cu，Au+Au和U+U碰撞相比，结果显示了系统的尺寸依赖性。
We report the elliptic flow ($v_{2}$) of $K_{s}^{0}$, $Λ$, $\barΛ$, $ϕ$, $Ξ^{-}$, and $\overlineΞ^{+}$ at mid-rapidity for Ru+Ru and Zr+Zr collisions at $\sqrt{s_{\mathrm {NN}}}$ = 200 GeV. The transverse momentum ($p_{T}$) and centrality dependence of $v_{2}$ have been studied. The number of constituent quark (NCQ) scaling for all the (multi-)strange hadrons has also been tested. The dependence in the ratio of average $v_{2}$ ($\langle$$v_{2}$$\rangle$) on centrality shows a deviation from unity indicating a difference in nuclear structure and deformation between the isobars. The results show a systematic size dependence when compared to Cu+Cu, Au+Au, and U+U collisions at similar beam energies.
