论文摘要
我们计算了200 GEV AU+AU中Hyperbs的局部自旋极化的方位角依赖性和2.76 TEV PB+PB碰撞在（3+1）D粘性水力动力学模型的框架中使用AMPT的AMPT初始条件，编码初始轨道Angular Momenta。我们发现，超子极化的方位角依赖性在很大程度上取决于旋转化学势$ω_{μν} $的选择。选择$ω_{μν} $与温度涡度成正比，我们的仿真显示了与最新测量结果的巧合结果。
We calculated the azimuthal angle dependence of the local spin polarization of hyperons in 200 GeV Au+Au and 2.76 TeV Pb+Pb collisions in the framework of the (3+1)D viscous hydrodynamic model CLVisc with AMPT initial conditions encoding initial orbital angular momenta. We find that the azimuthal angle dependence of the hyperon polarization strongly depends on the choice of the spin chemical potential $Ω_{μν}$. With $Ω_{μν}$ chosen to be proportional to the temperature vorticity, our simulation shows coincidental results with the recent measurements at RHIC.
