Abstract

We study higher-order QCD corrections beyond NLO for the associated production of a photon with a W boson (γW⁺ and γW^- production) at the Large Hadron Collider. We calculate the NNLO soft-plus-virtual QCD corrections as well as the N³LO 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 N³LO in single-particle-inclusive kinematics for a Standard Model process.
