论文摘要
在强子山子上产生的带电量规玻色子的产生是提取电子参数和对质子结构的理解的基本基准。为了实现此过程的精确现象学，我们将QCD校正（n $^3 $ LO）校正计算到W Boson生产中的速度分布和电荷不对称性以及其衰减产物的横向质量分布。我们的结果显示了与Tevatron和LHC测量相关的运动区域中的大量QCD校正。我们将N $^3 $ LO校正的数值大小与Electroweak输入参数的不确定性进行了比较，并量化了其对W Boson质量测定的潜在影响。
Charged gauge boson production at hadron colliders is a fundamental benchmark for the extraction of electroweak parameters and the understanding of the proton structure. To enable precision phenomenology for this process, we compute the third-order (N$^3$LO) QCD corrections to the rapidity distribution and charge asymmetry in W boson production and to the transverse mass distribution of its decay products. Our results display substantial QCD corrections in kinematic regions relevant for Tevatron and LHC measurements. We compare the numerical magnitude of the N$^3$LO corrections with uncertainties from electroweak input parameters and quantify their potential impact on the determination of the W boson mass.
