论文摘要

我们将混合的QCD-ElectRoweak校正计算为On-Shell $ W $ BOSON的完全不同的生产。领先顺序近似中包括$ W $玻色子的损伤。根据Electroweak仪表玻色子质量的任意值,对所需的两循环虚拟校正进行分析计算。在优化的软共线减法方案中获得了综合减法项的分析结果,以适应混合QCD-ElectRoweak贡献的不良奇异性的结构简单性。在此过程中介绍了将$ pp \至w^+ \至w^+ \至w^+ \ $ pp \ of $ pp \ of $ pp \的基准横截面的数值结果以及在此过程中选定的运动分布。

We compute mixed QCD-electroweak corrections to the fully-differential production of an on-shell $W$ boson. Decays of $W$ bosons to lepton pairs are included in the leading order approximation. The required two-loop virtual corrections are computed analytically for arbitrary values of the electroweak gauge boson masses. Analytic results for integrated subtraction terms are obtained within a soft-collinear subtraction scheme optimized to accommodate the structural simplicity of infra-red singularities of mixed QCD-electroweak contributions. Numerical results for mixed corrections to the fiducial cross section of $pp \to W^+ \to l^+ ν$ and selected kinematic distributions in this process are presented.
