论文摘要
在相对论重离子对撞机（RHIC）和大型强子对撞机（LHC）上的最新实验表明，在非中心重离子碰撞中包含奇怪的夸克的黑核可以两极化。我们详细研究了使用Proca方程的自旋和涡度的旋转和涡度耦合，并通过单一的折叠 - Wouthuysen转换提供了野外方程的非层次性降低。我们发现由此产生的哈密顿式不是热的人，而是$ {\ cal pt} $不变的，并且涉及一个旋转的术语$ \ textStyle {\ frac {\ frac {1} {2}}}}} s_z \ hbarω$在涡流中领先订单。我们还计算了对哈密顿量的进一步相对论和量子校正。
Recent experiments at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) have indicated that hadrons containing strange quarks produced in non-central heavy ion collisions can be polarized. We investigate in detail the coupling of spin and vorticity for electrically neutral, massive vector bosons using the Proca equation, and provide the nonrelativistic reduction of the field equations via a single Foldy--Wouthuysen transformation. We find that the resulting Hamiltonian is not-Hermitian, but ${\cal PT}$ invariant, and involves a spin dependent term $\textstyle{\frac{1}{2}} s_z \hbar ω$ to leading order in vorticity. We also calculate further relativistic and quantum corrections to the Hamiltonian.
