横向流体动力学的一般公式

General formulation of transverse hydrodynamics

Radoslaw Ryblewski, Wojciech Florkowski

摘要:

本文给出了描述超相对论性重离子碰撞早期产生的横向热化物质的流体力学一般公式。与标准的三维热化相对论流体力学的异同进行了讨论。守恒定律的作用,以及二维热力学变量表征横向热化物质的热力学一致性被强调。

英文摘要:

General formulation of hydrodynamics describing transversally thermalized matter created at the early stages of ultra-relativistic heavy-ion collisions is presented. Similarities and differences with the standard three-dimensionally thermalized relativistic hydrodynamics are discussed. The role of the conservation laws as well as the thermodynamic consistency of two-dimensional thermodynamic variables characterizing transversally thermalized matter is emphasized.
