椭圆流聚结法鉴别$f_{0}$（980）含量
Elliptical flow coalescence to identify the $f_{0}$(980) content
摘要：
我们用一个简单的聚结模型生成了三种构型的$f_{0}$（980）粒子：${s\bar{s}}$介子、${u\bar{u}s\bar{s}}$四夸克态和${K^{+}K^{-}}$分子。聚结组分的相空间信息取自重离子碰撞的多相输运（AMPT）模拟。结果表明，椭圆流各向异性的组分夸克数标度可以用来区分${s\bar{s}}$从${u\bar{u}s\bar{s}}$和${K^{+}K^{-}}$配置。
英文摘要：
We use a simple coalescence model to generate $f_{0}$(980) particles for three configurations: a ${s\bar{s}}$ meson, a ${u\bar{u}s\bar{s}}$ tetraquark, and a ${K^{+}K^{-}}$ molecule. The phase-space information of the coalescing constituents is taken from a multi-phase transport (AMPT) simulation of heavy-ion collisions. It is shown that the number of constituent quarks scaling of the elliptic flow anisotropy can be used to discern ${s\bar{s}}$ from ${u\bar{u}s\bar{s}}$ and ${K^{+}K^{-}}$ configurations.
