论文摘要
我们提出了最新的高精度理论预测，以参数为主要角度系数，以参数化在大于30 GEV的横向动量下产生的W - 玻璃体的生产和衰减中的自旋相关性。将NNLO QCD和NLO EW精度的计算合并，以获得W玻璃横向动量和速度的差分分布。发现的结果在某些相空间区域显示了多达10％的校正，而与NLO QCD相比，比例谱带显着降低。
We present state-of-the-art high-precision theory predictions for the dominant angular coefficients parametrizing the spin-correlations in the production and decay of a W-boson produced at transverse momentum larger than 30 GeV. The computation at NNLO QCD and NLO EW accuracy are combined to obtain differential distributions in the W-boson transverse momentum and rapidity. The found results show up to 10 % corrections in certain regions of phase space, while the scale bands are significantly reduced as compared to NLO QCD.
