Description

We calculate fixed-order electroweak corrections to the angular coefficients parameterizing the Drell-Yan process in the Z-boson mass range. We examine how the electroweak corrections affect the Lam-Tung relation, which was measured at the LHC to deviate from the SM predictions. For the calculations, we introduce a technical single lepton cut in order to avoid a double-soft/collinear singularity in the electroweak corrections. We investigate how the size of this cut alters the NLO electroweak and NLO QCD corrections to the coefficients and the Lam-Tung relation.
