Abstract (data abstract)
CERN-LHC. Fiducial and differential measurements of $W^+W^-$ production in events with at least one hadronic jet are presented. These measurements are sensitive to the properties of gauge boson self interactions and provide a test of perturbative quantum chromodynamics and the electroweak theory. The analysis is performed using proton--proton collision data collected at $\sqrt{s}=13$ TeV with the ATLAS experiment, corresponding to an integrated luminosity of 139 fb$^{-1}$. Events with exactly one oppositely charged electron-muon pair and at least one hadronic jet with a transverse momentum of $p_{\mathrm{T}}>30$ GeV and a pseudorapidity of $|\eta|<4.5$ are selected. After subtracting the background contributions and correcting for detector effects, the fiducial cross-section and the differential cross-sections with respect to several kinematic variables are measured. These measurements include leptonic quantities, like the lepton transverse momenta as well as the transverse mass of the $WW$ system, and also jet related observables like the leading jet transverse momentum and the jet multiplicity. Limits on anomalous triple gauge couplings are obtained in a phase space where the interference between Standard Model and the anomalous amplitude is enhanced.
