论文摘要
沿伪层的谐波流动的波动，称为流动性，是对夸克 - 胶原等离子体的初始状态几何形状的重要探针。流动去相关被证明对碰撞核的集体结构很敏感，如比较异荷斯的碰撞，$^{96} $ ru+$+$+$^{96} $ ru和$^{96} $^{96} $ zr+$^{96} $ zr，它们具有不同的核结构。中央碰撞中的流动解相关主要对核变形敏感，而中南部碰撞中的流量则主要对$^{96} $ ru和$^{96} $ zr之间的皮肤厚度差异敏感。重离子碰撞中的纵向流动性是探测碰撞核结构的新工具。
Fluctuations of harmonic flow along pseudorapidity, known as flow decorrelations, are an important probe of the initial state geometry of the quark-gluon plasma. The flow decorrelations are shown to be sensitive to the collective structure of the colliding nuclei, as revealed clearly by comparing collisions of isobars, $^{96}$Ru+$^{96}$Ru and $^{96}$Zr+$^{96}$Zr, which have different nuclear structures. The flow decorrelations in central collisions are mostly sensitive to nuclear deformations, while those in the mid-central collisions are primarily sensitive to differences in skin thickness between $^{96}$Ru and $^{96}$Zr. Longitudinal flow decorrelations in heavy-ion collisions are a new tool to probe the structure of colliding nuclei.
