Higher-order soft and virtual corrections in $$p p \rightarrow \gamma W$$ production at the LHC
Year: 2025
Type: article
Abstract: We study higher-order QCD corrections beyond NLO for the associated production of a photon with a W boson ( $$\gamma W^+$$ γ W + and $$\gamma W^-$$ γ W - production) at the Large Hadron Collider. We calculate the NNLO soft-plus-virtual QCD corrections as well as the $$\hbox {N}^3$$ N 3 LO soft-gluon corrections to the total production cross section and the photon transverse-momentum distribution in single-particle-inclusive kinematics. The higher-order corrections provide a significant enhancement to the cross section. This is the first calculation of the complete soft-gluon corrections at $$\hbox {N}^3$$ N 3 LO in single-particle-inclusive kinematics for a Standard Model process.
