论文摘要
HADRON COLLIDERS的电流电流YAN生产是一个基准Electroweak工艺。 CDF实验对W玻色子质量的最新测量显示出与标准模型预测的较大偏差。为了实现此过程的精确现象学，我们将QCD校正（n $^3 $ LO）校正计算为W玻色子生产的速度分布以及其衰减产物的横向质量分布。我们研究与LHC实验相关的运动区域，并评估Electroweak输入参数和Parton分布功能的不确定性的数值幅度。
Charged current Drell-Yan production at hadron colliders is a benchmark electroweak process. A recent measurement of the W boson mass by the CDF experiment displays a large deviation from the Standard Model prediction. To enable precision phenomenology for this process, we compute the third-order (N$^3$LO) QCD corrections to the rapidity distribution in W boson production and to the transverse mass distribution of its decay products. We study kinematic regions relevant for the LHC experiments and assess the numerical magnitude of uncertainties from electroweak input parameters and parton distribution functions.
