论文摘要
我们简要回顾了一种最近提出的与自旋的完美流体流体动力学的形式主义，这是标准流体动力框架的概括，并提供了一种自然工具来描述具有自旋1/2的颗粒的自旋偏振系统的演变。它基于De Groot -Van Leeuwen -Van Weert的能量摩托车形式，旋转张量和保护定律。使用Bjorken对称性，我们显示了如何使用这种形式主义来确定实验中测得的颗粒的极化的可观察结果。
We briefly review a recently proposed formalism of perfect-fluid hydrodynamics with spin, which is a generalization of the standard hydrodynamic framework and provides a natural tool for describing the evolution of spin-polarized systems of particles with spin 1/2. It is based on the de Groot - van Leeuwen - van Weert forms of energy-momentum and spin tensors and conservation laws. Using Bjorken symmetry we show how this formalism may be used to determine observables describing the polarization of particles measured in the experiment.
