摘要

我们概述了在双环水平的大型强子对撞机上产生单向量玻色子的混合EW-QCD校正的计算细节。利用微分方程的新方法得到了纯虚积分、实虚积分和双实积分。最后，我们得到了qq→Z + X过程总分子截面的0 (α αs)修正。

NNLO mixed EW-QCD corrections to single vector boson production

We outline the computational details to obtain mixed EW-QCD corrections to on-shell production of a single vector boson at the LHC at two-loop level. We use the novel method of differential equation to obtain the pure virtual, real-virtual and double-real master integrals. Finally, we obtain the O(α αs) corrections to the total partonic cross section of the process qq → Z + X.
