چکیده    We calculate the process $$ ppto {w}^{+}{w}^{-}to {e}^{+}{nu}_e{mu}^{-}{overline{nu}}_{mu } $$ 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.
