论文摘要
当顶部夸克高度增强时,其衰减中的$ W $玻色子具有很大的线性极化,从而导致顶级衰减产品之间的$ \ cos 2ϕ $方位角相关性。我们表明,可以测量这种相关性的强化衰减的升压顶部,并且其幅度提供了一种测量顶夸克的纵向极化的方法,这是对新物理学的重要探测,这些物理学是将耦合到顶部扇形的。
When a top quark is highly boosted, the $W$ boson from its decay has a substantial linear polarization that results in a $\cos 2ϕ$ azimuthal angular correlation among the top decay products. We show that this correlation can be measured for hadronically decayed boosted tops, and its magnitude provides a way to measure the longitudinal polarization of top quark, which is an important probe of new physics that couples to top sector.
