当顶夸克衰变时，在它的静止坐标系中，它的自旋方向和衰变后带电轻子的飞行方向之间存在大量的角相关。在本文中，我们调查的前景，测量这种角相关使用MC@NLO框架。不同的自旋基地的相关性的强度进行了研究。部分子分布函数集和不确定性，因子分解尺度依赖性，质心能量和射流R参数的变化的鲁棒性也进行了研究。
When a top quark decays there is a large amount of angular correlation, in its rest frame, between its spin orientation and the direction of flight of the charged lepton from its decay. In this paper we investigate the prospects of measuring this angular correlation using the MC@NLO framework. The strength of the correlation is investigated for different spin bases. The robustness against variation of parton distribution function sets and uncertainties, factorization scale dependence, center-of-mass energy, and the jet R-parameter is also examined.
