Abstract
We calculate the process \( pp\to {W}^{+}{W}^{-}\to {e}^{+}{\nu}_e{\mu}^{-}{\overline{\nu}}_{\mu } \) at NLO QCD, including also effective field theory (EFT) operators mediating the ggW + W − interaction, which first occur at dimension eight. We further combine the NLO and EFT matrix elements produced by GoSam with the Herwig7/Matchbox framework, which offers the possibility to study the impact of a parton shower. We assess the effects of the anomalous couplings by comparing them to top-mass effects as well as uncertainties related to variations of the renormalisation, factorisation and hard shower scales.
