An adequate description of the neutral-current Drell-Yan process at the Tevatron and the LHC, in particular, requires the inclusion of electroweak radiative corrections. We extend earlier work in this direction in various ways. First, we define and numerically compare different methods to describe the Z-boson resonance including next-to-leading order electroweak corrections; moreover, we provide explicit analytical expressions for those. Second, we pay particular attention to contributions from γγ and γ-quark collisions, which involve photons in the initial state, and work out how their impact can be enhanced by selection cuts. Third, we supplement the $$ \mathcal{O} $$(α) corrections by universal electroweak effects of higher order, such as universal two-loop contributions from ∆α and ∆ρ, and the leading two-loop corrections in the high-energy Sudakov regime as well as multi-photon radiation off muons in the structure-function approach. Finally, we present results on the complete next-to-leading order electroweak and QCD corrections within the minimal supersymmetric extension of the Standard Model.

Next-to-leading-order electroweak corrections to the production of four charged leptons at the LHC (2016, methodology): “gh for the Higgs-speciﬁc setup), the EW corrections largely resemble the known structure of the photonic and weak corrections to Drell–Yan-like single-Z production, which are, e.g., discussed in Ref. [54] (cf. Fig. 12 therein). Let us ﬁrst analyze the right column of Fig. 7. The weak corrections sta”
