NNLO mixed EW-QCD corrections to single vector boson production

Key Points

Mixed EW-QCD corrections to vector boson production enhance the accuracy of theoretical predictions.
The process qq ̄ → Z + X demonstrates significant corrections at the two-loop level, impacting total cross-section calculations.
Analysis employs differential equations to derive master integrals across virtual and real emissions.
These corrections may improve precision in collider physics applications, enhancing future experiments at the LHC.

Abstract

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(ααs) corrections to the total partonic cross section of the process qq ̄ → Z + X.
