论文摘要
我们评估了基于保形弛豫时间近似中玻尔兹曼方程的微观动力学描述中高能重型离子碰撞中集体流动的全部不透明度依赖性。通过将动力学理论计算与流体动力学和混合模拟的平均初始状态进行比较，我们指出了流体动力学模型的缺点和不准确性，并提出了改进的模拟设置以改善它们。
We evaluate the full opacity dependence of collective flow in high-energy heavy-ion collisions within a microscopic kinetic description based on the Boltzmann equation in the conformal relaxation time approximation. By comparing kinetic theory calculations to hydrodynamic and hybrid simulations for an average initial state, we point out shortcomings and inaccuracies of hydrodynamic models and present modified simulation setups to improve them.
