# Anomalous coupling, top-mass and parton-shower effects in $W^+W^−$ production

Bellm, J; Gieseke, S; Greiner, N; Heinrich, G; Plätzer, S; Reuschle, C; von Soden-Fraunhofen, J F (2016). Anomalous coupling, top-mass and parton-shower effects in $W^+W^−$ production. Journal of High Energy Physics, 2016(5):1-24.

## Abstract

We calculate the process $pp\to W^+W^-\to e^+ \nu_e \mu^-\bar{\nu}_\mu$ 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.
