论文摘要
相对论重型离子碰撞的演变通常被理解为将系统的初始几何形状传输到观察到的Hadron的最终动量分布中的过程，可以通过能量密度的初始分布的累积扩展来描述，并以领先顺序表示为Anisotropic Flow的偏心量表。我们总结了该框架的提议扩展，以包括在能量巨头张量的其他组件中编码的初始动量空间特性的贡献。数值测试验证了该建议。
The evolution of a relativistic heavy-ion collision is typically understood as a process that transmutes the initial geometry of the system into the final momentum distribution of observed hadrons, which can be described via a cumulant expansion of the initial distribution of energy density and is represented at leading order as the well-known eccentricity scaling of anisotropic flow. We summarize a proposed extension of this framework to include the contribution from initial momentum-space properties, as encoded in other components of the energy-momentum tensor. Numerical tests validate this proposal.
