论文摘要
我们研究了在强子山脉散射的巨大电动玻色子散射中带正电荷的$ W $的极化。我们依靠蒙特卡洛模拟中幅度不变的，双共振部分的弱玻色子极化的分离。极化取决于定义它们的参考框架。我们讨论了极化分数和运动学分布的变化，这是由于在最近的实验分析中使用的两个不同的参考帧中定义极化向量而产生的。
We study the polarization of positively charged $W$'s in the scattering of massive electroweak bosons at hadron colliders. We rely on the separation of weak boson polarizations in the gauge-invariant, doubly-resonant part of the amplitude in Monte Carlo simulations. Polarizations depend on the reference frame in which they are defined. We discuss the change in polarization fractions and in kinematic distributions arising from defining polarization vectors in two different reference frames which have been employed in recent experimental analyses.
