论文摘要
从强子 - 哈德隆碰撞中提取W-Boson质量是标准模型的基本参数，需要精确的理论预测。在这方面，角系数对于建模W玻璃体产生的动力学至关重要。在这项工作中，我们首次在NNLO QCD + NLO EW精度下为LHC的有限横向动量W-Boson提供角系数。在某些相空间区域，校正最多可达到10％。它们伴随着量表不确定性的显着降低。除了为理论数据比较提供参考值外，还应为W-Boson质量测量提供最新的理论输入。
The extraction of the W-boson mass, a fundamental parameter of the Standard Model, from hadron-hadron collision requires precise theory predictions. In this regard, angular coefficients are crucial to model the dynamics of W-boson production. In this work, we provide, for the first time, angular coefficients at NNLO QCD + NLO EW accuracy for finite transverse momentum W-boson at the LHC. The corrections can reach up to 10% in certain regions of phase space. They are accompanied by a significant reduction of the scale uncertainty. This work should, besides providing reference values for theory-data comparison, provide state-of-the-art theory input for W-boson mass measurements.
