Coupling hadronic kinetic theory models to fluid dynamics in phenomenological studies of heavy ion collisions requires a prescription for “particlization”. Existing particlization models are based on implicit or explicit assumptions about the microscopic degrees of freedom that go beyond the information provided by the preceding fluid dynamical history. We propose an alternative prescription which uses only macroscopic information provided by the hydrodynamic output. This method follows directly from the connections between information theory and statistical mechanics.

重离子碰撞的最大熵动力学匹配条件

在重离子碰撞的现象学研究中将强子动力学理论模型与流体动力学耦合需要“粒子化”的处方。现有的粒子化模型基于对微观自由度的隐式或显式假设，这些假设超出了先前流体动力学历史提供的信息。我们提出了一种替代方案，它仅使用流体动力输出提供的宏观信息。这种方法直接来自信息论和统计力学之间的联系。
