论文摘要
我们研究了Wigner功能的不同组件的$ M = 0 $限制。与手性动力学理论相比,我们将矢量和轴向矢量成分的消失部分和非变化部分分开,直至$ \ hbar $的一阶。然后,我们讨论了消失和非变化部分的物理含义,以及它们在热平衡时的不同行为。
We studied the $m=0$ limit of different components of Wigner functions for massive fermions. Comparing with the chiral kinetic theory, we separated the vanishing part and non-vanishing part for vector and axial vector components, up to the first order of $\hbar$. Then we discussed the possible physical meaning of the vanishing and non-vanishing parts, and their different behavior at thermal equilibrium.
