摘要
重离子碰撞中产生的受激和压缩核物质在广泛的入射能量范围内的膨胀和衰变在很大程度上取决于集体流动。流体力学理论表明,核物质的流体行为会在粒子发射中产生很大的方位相关性。发现核物质可压缩性以及间接发现核状态方程的最大机会是通过对集合流的精确测量。使用方位角相关函数评估了\(^{84}\)Kr在1 A GeV与乳状液(复合靶)和Ag(Br)靶相互作用时产生的电荷为\(N_{\text {PF}}\ge 3\) 和\(N_{\alpha }\ge 3\) 的射弹碎片(PFs)的集体流。在半中心碰撞中,集体流最为明显。根据我们的观察,集体流的振幅在相对论能量下似乎相当稳定。此外,我们还将所得结果与其他现有实验数据进行了比较。
Utilize azimuthal correlation to examine the collective flow influence caused by the reaction between \(^{84}\)Kr nuclei and emulsion nuclei at 1 A GeV
The expansion and decay of excited and compressed nuclear matter produced in heavy-ion collisions across a broad range of incident energies are largely dependent on collective flow. Hydrodynamic theories suggest that the fluid-like behavior of nuclear matter produces a substantial azimuthal correlation in the particle emission. The greatest opportunity to discover nuclear matter compressibility and, indirectly, the nuclear equation of state is through precise measurements of collective flow. The collective flow of projectile fragments (PFs) of charge \(Z\ge 2\) produced in \(^{84}\)Kr in interacts with emulsion (composite target) and Ag(Br) target at 1 A GeV for \(N_{\text {PF}}\ge 3\) and \(N_{\alpha }\ge 3\) has been evaluated using azimuthal correlation functions. The collective flow is observed to be the most pronounced in semi-central collisions. The amplitude of the collective flow appears to be pretty stable at relativistic energy, according to our observation. Additionally, the obtained outcomes are compared to other existing experimental data.
