相对论性重离子碰撞中的横向流体力学

Transverse hydrodynamics in relativistic heavy-ion collisions

Radoslaw Ryblewski

摘要:

描述横向热化物质的流体动力学演化的形式主义的一般特征可能产生于超相对论性重离子碰撞的非常早期的阶段。强调了模型的热力学一致性。导出了相空间分布函数矩的协变公式。提出了从纯横向流体力学到标准理想流体力学过渡的简单模型。

英文摘要:

General features of the formalism describing hydrodynamic evolution of transversally thermalized matter possibly produced at the very early stages of ultra-relativistic heavy-ion collisions are presented. Thermodynamical consistency of the model is emphasized. The covariant formulas for the moments of the phase-space distribution function are derived. The simple model for the transition from purely transverse to standard perfect-fluid hydrodynamics is proposed.
