A bstractWe present the key features relevant to the automated computation of all the leading- and next-to-leading order contributions to short-distance cross sections in a mixed-coupling expansion, with special emphasis on the first subleading NLO term in the QCD+EW scenario, commonly referred to as NLO EW corrections. We discuss, in particular, the FKS subtraction in the context of a mixed-coupling expansion; the extension of the FKS subtraction to processes that include final-state tagged particles, defined by means of fragmentation functions; and some properties of the complex mass scheme. We combine the present paper with the release of a new version of MadGraph5_aMC@NLO, capable of dealing with mixed-coupling expansions. We use the code to obtain illustrative inclusive and differential results for the 13-TeV LHC.

Electroweak radiative corrections for collider physics (2019, methodology): “While only a few processes at Tevatron, such as the Drell–Yan-like production of Z or W bosons, required the inclusion of EW radiative corrections in predictions, the higher luminosity and the deeper energy reach of the LHC render EW corrections to all major processes important or at least relevant ”
