Abstract 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.

LHC 同符号 WW 散射中的不同极化定义

摘要 我们研究了强子对撞机中大量电弱玻色子散射中带正电的 W 的极化。我们依赖于蒙特卡罗模拟中振幅的规范不变、双共振部分中弱玻色子极化的分离。偏振取决于定义它们的参考系。我们讨论了在最近的实验分析中使用的两个不同参考系中定义偏振矢量所引起的偏振分数和运动学分布的变化。
