论文摘要
在本文中,我们通过最近提出的旋转框架回顾了完美的流体动力学。该框架将标准的相对论水动力学框架概括为包括自由度的自由度,并提供了一种自然方法来描述大量自旋1/2颗粒的自旋极化演化。这种形式主义基于GLW(de Groot -van Leeuwen -van Weert)能量量张量和自旋张量。我们在这里使用Bjorken模型显示,该自旋流体动力学框架如何用于确定可观察到的物体,该可观测值描述了实验中测得的粒子极化。
In this article we review the perfect-fluid hydrodynamics with spin framework proposed recently. This framework generalises the standard relativistic hydrodynamics framework to include spin degrees of freedom and provides a natural method to describe the spin polarization evolution of massive spin 1/2 particles. This formalism is based on the GLW (de Groot - van Leeuwen - van Weert) energy-momentum tensor and spin tensor. We show here using Bjorken model that how this spin hydrodynamics framework may be used for the determination of the observables which describes the particle polarization measured in the experiment.
