论文摘要
已证明，受局部电荷保护的约束驱动的相关性可洞悉对超偏见的重离子碰撞中产生的高温物质的化学演化和扩散。由最终状态相互作用驱动的两粒子相关性已使有关相同碰撞的扩展和溶解的关键触发时空信息提出。最终互动的相关性主要出现在小相对动量，而几十MEV/$ C $，而电荷平衡相关性扩展到数百个MEV/$ C $的范围。在几乎所有以前的分析中，这种量表的分离都用于仅专注于一个类别或另一个类。这项研究的目的是定量了解最终状态相互作用的相关性扭曲了电荷平衡相关性的解释，反之亦然。
Correlations driven by the constraints of local charge conservation have been shown to provide insight into the chemical evolution and diffusivity of the high-temperature matter created in ultra-relativistic heavy ion collisions. Two-particle correlations driven by final-state interactions have allowed the extraction of critical femtoscopic space-time information about the expansion and dissolution of the same collisions. Whereas correlations from final-state interactions mainly appear at small relative momenta, a few tens of MeV/$c$, charge-balance correlations extend over a range of hundreds of MeV/$c$. In nearly all previous analyses, this separation of scales is used to focus solely on one class or the other. The purpose of this study is to quantitatively understand the degree to which correlations from final-state interactions distort the interpretation of charge-balance correlations and vice versa.
