标题： Test of $CP$ Violating Neutral Gauge Boson Vertices in $ e^+ e^- \rightarrow γZ $

摘要： 过程$e^+ e^- \rightarrow \gamma Z$的正反不对称性被提出作为检验$CP$ - 违反的异常$\gamma \gamma Z$和$ \gamma Z Z$耦合的测试方法。 纵向极化的电子束可用于区分这些耦合的影响。 我们估计在质心系能量为 200 GeV 和 500 GeV 的$e^+ e^-$对撞机上可以获得的可能限制。 显示英文摘要

摘要： Forward-backward asymmetry in the process $e^+ e^- \rightarrow \gamma Z$ is proposed as a test for $CP$--violating anomalous $\gamma \gamma Z$ and $ \gamma Z Z$ couplings. Longitudinally polarized electron beams may be used to disentangle the effects of these couplings. We estimate possible limits that can be obtained from $e^+ e^-$ colliders at centre-of-mass energies of 200 GeV and 500 GeV.
