Title: QCD corrections in Standard Model EFT fits to W Z and W W production

Abstract

We investigate the role of anomalous gauge boson and fermion couplings in the production of W Z and W + W pairs at the LHC to next-to-leading-order (NLO) QCD in the Standard Model effective field theory (SMEFT), including dimension-six operators. Our results are implemented in a publicly available version of the powheg-box. We combine our W Z results in the leptonic final state eνμ +μ with previous W + W results to demonstrate the numerical effects of NLO QCD corrections on the limits on effective couplings derived from ATLAS and CMS 8 and 13 TeV differential measurements. Our study demonstrates the importance of including NLO QCD SMEFT corrections in the W Z analysis, while the effects on W W production are smaller. We also show that the O(1/Λ 4) contributions dominate the analysis, where Λ is the high-energy scale associated with the SMEFT.
