Abstract

Employing the AMPT transport model, we investigate the response of the rapidity-even dipolar flow ( ) and its associated Global Momentum Conservation (GMC) parameter K to structural disparities within 96Ru and 96Zr nuclei. We analyze Ru + Ru and Zr + Zr collisions at a center-of-mass energy of = 200 GeV. Our analysis demonstrates that the eccentricity ε1, and K exhibit subtle yet discernible sensitivity to the input nuclear structure distinctions between 96Ru and 96Zr isobars. This observation suggests that measuring and the GMC parameter in these isobaric collisions could serve as a means to fine-tune the comprehension of their nuclear structure disparities and offer insights to enhance the initial condition assumptions of theoretical models.

探索 RHIC 等边碰撞中的快速偶极流

我们利用 AMPT 输运模型，研究了快速偶极流（）及其相关的全局动量守恒（GMC）参数 K 对 96Ru 和 96Zr 核内结构差异的响应。我们分析了质量中心能量 = 200 GeV 的 Ru + Ru 和 Zr + Zr 对撞。我们的分析表明，偏心率ε1和K对输入的96Ru和96Zr等轴核结构差异具有微妙而明显的敏感性。这一观察结果表明，在这些等压对撞中测量 GMC 参数可以作为一种手段来微调对其核结构差异的理解，并为增强理论模型的初始条件假设提供启示。
