我们建立了具有纵向增强不变性的手性动力学方程。我们特别关注粒子数守恒的物理解释。出现了与展开相关的两项，这在非手性动力学方程中不存在。一是侧跳效应对横向电流的贡献，二是密度的变化，其流动导致纵向电流。我们指出了由膨胀驱动的横向电流的特征模式，我们称之为手性圆位移。
We formulate the chiral kinetic equation with the longitudinal boost invariance. We particularly focus on the physical interpretation of the particle number conservation. There appear two terms associated with the expansion, which did not exist in the non-chiral kinetic equation. One is a contribution to the transverse current arising from the side-jump effect, and the other is a change in the density whose flow makes the longitudinal current. We point out a characteristic pattern in the transverse current driven by the expansion, which we call the chiral circular displacement.
