标题： Polarization effects in electroweak vector boson productions

摘要： 矢量玻色子的弱电生产过程，$e^+ e^- \rightarrow Z \gamma$，$\gamma e \rightarrow Ze$，和$\gamma e \rightarrow W \nu$是同时考虑的，在标准模型中，这些过程的矢量玻色子协变极化密度矩阵是从其中一个过程，$\gamma e \rightarrow Z e$明确得到的。 光子极化以及矢量介子极化的效应被考虑，并讨论了一些特殊情况。 显示英文摘要

摘要： The electroweak production processes of vector bosons, $e^+ e^- \rightarrow Z \gamma$, $\gamma e \rightarrow Ze$, and $\gamma e \rightarrow W \nu$ are considered simultaneousely and in the Standard model the covariant polarization density matrices of vector bosons for these processes are obtained explicitly from one of the processes, $\gamma e \rightarrow Z e$. The effect of the photon polarization as well as the vector meson polarization is considered and some special cases are discussed.
