论文摘要
我们列举了各种有效的耦合，这些耦合有助于异国情调的矢量玻色子$ z^{\ prime} $与中性的电动电动载体玻色子之间的混合。杂项混合模式可以扰动地评估。计算有效的倾斜参数$ s^{\ prime} $，$ t^{\ prime} $和$ u^{\ prime} $与electroweak Precision测试结果进行了比较。从$ε_{b，w} $参数和其他一些参数的帮助中，可以解释来自$ε_{b，w} $参数的不可忽视的$ u^{\ prime} $参数的贡献。
We enumerate various effective couplings that contribute to the mixings between an exotic vector boson $Z^{\prime}$ and the neutral electroweak vector bosons. The miscellaneous mixing patterns can be evaluated perturbatively. The effective oblique parameters $S^{\prime}$, $T^{\prime}$, and $U^{\prime}$ are calculated to compare with the electroweak precision test results. With the contributions to the non-negligible $U^{\prime}$ parameter from the $ε_{B,W}$ parameters and the aid of some other parameters to cancel the negative $T^{\prime}$, the recent CDF $W$-mass anomaly can therefore be explained.
