摘要
我们概述了我们对强子碰撞中W +射流产生的次-次-前序(NNLO) QCD修正的计算。将多重差分分布的现象学结果与8tev质子-质子碰撞的CMS数据进行了比较。我们进一步讨论了计算在包含W玻色子产生的横向动量谱中的应用，并再次与8 TeV CMS数据进行了比较。在这两种情况下，包含NNLO QCD效应的理论和数据之间的一致性得到了改善，相对于次领先阶(NLO)结果，尺度不确定性大大降低。
NNLO QCD Corrections to W+jet Production in NNLO JET
We give an overview of our calculation of the next-to-next-to-leading order (NNLO) QCD corrections to W + jet production in hadronic collisions. Phenomenological results for multiple differential distributions are compared to CMS data for 8 TeV proton–proton collisions. We further discuss the application of the calculation to the transverse momentum spectrum of inclusive W boson production, again accompanied by a comparison to 8 TeV CMS data. In both cases, the inclusion of NNLO QCD effects give an improved agreement between theory and data with considerably reduced scale uncertainties with respect to the next-to-leading order (NLO) results.
