Power corrections in a transverse-momentum cut for vector-boson production at NNLO: the qg-initiated real-virtual contribution

We consider the production of a vector boson ( Z , W ± or γ ∗ ) at next-to-next-to-leading order in the strong coupling constant α S . We impose a transverse-momentum cutoff, q T cut , on the vector boson produced in the qg -initiated channel. We then compute the power corrections in the cutoff, up...
