摘要

我们回顾了最近引入的具有1 / 2自旋的粒子的完美流体流体动力学方程的基本成分。对于一个准真实的设置，首先给出了包括自旋极化张量在内的各种流体动力变量的数值解。我们的结果表明，最热区的初始自旋极化可能在冻结时粒子的极化中起主导作用。

Relativistic fluid dynamics of spin-polarized systems of particles

We review basic ingredients of the recently introduced perfect-fluid hydrodynamic equations for particles with spin one-half. For a quasi-realistic setup, first numerical solutions for various hydrodynamic variables including the spin polarization tensor are presented. Our results indicate that the initial spin polarization of the hottest region may play a dominant role in the polarization of particles at freeze-out.
