论文摘要
在这些程序中，我讨论了相对论流体中自旋极化理论的最新进展。迄今为止，许多研究已经开始研究剪切张量对局部自旋极化的影响，以及该贡献是否可以恢复测量值和从血浆梯度引起的极化获得的预测之间的一致性。我介绍了在局部热平衡处的fermion的自旋极化载体的推导，并讨论了伪规范转化和耗散效应的作用。我列出了我们可以从较低能量下测得的极化中学到的东西。最后，我讨论了自旋极化测量值在相对论重离子碰撞中的可能应用。
In these proceedings I discuss the recent progress in the theory of spin polarization in relativistic fluids. To date, a number of studies have begun to examine the impact of the shear tensor on the local spin polarization and whether this contribution can restore agreement between the measurements and the predictions obtained from a polarization induced by the gradients of the plasma. I present the derivation of the spin polarization vector of a fermion at local thermal equilibrium and I discuss the role of pseudo-gauge transformations and of dissipative effects. I list what we can learn from the polarization measured at lower energies. Finally, I discuss possible applications of spin polarization measurements in relativistic heavy ion collisions.
