论文摘要
多相传输（AMPT）模型用于研究形状工程事件的功效，以描述对高阶流量谐波$ v_ {4} $和$ v_ {5} $之间的线性和非线性贡献之间的耦合程度。该研究表明，非线性贡献是强大的，而线性贡献是与形状无关的，几乎没有表明线性和非线性流量系数之间的耦合。此类模式的实验验证可能是可鲁棒提取线性和模式耦合流量系数的宝贵工具，尤其是对于带电粒子多样性的光束能量，而发生统计量无法使用当前方法来建立耦合强度。
A Multi-Phase Transport (AMPT) model is used to study the efficacy of shape-engineered events to delineate the degree of coupling between the linear and nonlinear contributions to the higher-order flow harmonics $v_{4}$ and $v_{5}$. The study shows that the nonlinear contributions are strongly shape-dependent while the linear contributions are shape-independent, indicating little if any, coupling between the linear and nonlinear flow coefficients. The experimental verification of such patterns could be an invaluable tool for robust extraction of the linear and mode-coupled flow coefficients, especially for beam energies where the charged particle multiplicity and the event statistics precludes the use of current methods to establish the coupling strength.
