AI 中文摘要
超相对论轻离子碰撞中的各向异性流对碰撞核的初始几何形状敏感。我们研究在LHC能区的椭圆流测量是否能约束¹⁶O和²⁰Ne的α团簇核密度分布参数。采用混合框架IP-Glasma+MUSIC+iSS+UrQMD，我们模拟了质心系能量√s_NN=5.36 TeV下的OO和Ne-Ne碰撞，分别对应Woods-Saxon分布和具有不同团簇紧密度的α团簇构型。我们计算了ALICE、CMS和ATLAS探测器运动学接收度内的椭圆流系数v₂{2,|Δη|>1}，并与Run 3的OO和Ne-Ne实验测量结果进行比较。观察到末态椭圆流对核几何形状显著敏感，尤其在OO碰撞中，不同构型会导致v₂的中心度依赖和峰值位置存在差异。通过系统改变¹⁶O和²⁰Ne核的团簇尺寸和团簇间距，本研究试图确定与实验数据吻合最佳的团簇参数范围。这些结果表明，TeV能下轻离子碰撞中的流可观测量可用于优化轻核的核结构参数。
英文摘要
Anisotropic flow in ultra-relativistic light-ion collisions is sensitive to the initial geometry of the colliding nuclei. We investigate whether elliptic flow measurements can constrain the parameters of the proposed $α$-clustered nuclear density distributions of $^{16}$O and $^{20}$Ne at LHC energies. Using the hybrid framework IP-Glasma+MUSIC+iSS+UrQMD, we simulate OO and Ne--Ne collisions at $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV for the Woods--Saxon and $α$-clustered configurations with varying cluster compactness. The elliptic flow coefficient $v_2\{2,|Δη|>1\}$ is calculated in the kinematic acceptances of ALICE, CMS, and ATLAS detectors and is compared with the Run~3 OO and Ne--Ne experimental measurements. It is observed that the final-state elliptic flow is significantly sensitive to the nuclear geometry, especially in OO collisions, where different configurations lead to distinct centrality dependencies and peak positions of $v_{2}$. By performing a systematic variation of the cluster size and inter-cluster separation in $^{16}$O and $^{20}$Ne nuclei, this work attempts to identify the cluster parameter range that provides the best agreement with the experimental data. These results show that the flow observables in TeV-energy light-ion collisions can be used to optimize the nuclear structure parameters of light nuclei.
