These measurements are sensitive to the properties of electroweak-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 root s = 13TeV with the ATLAS experiment, corresponding to an integrated luminosity of 139 fb(-1). Events are selected with exactly one oppositely charged electron-muon pair and at least one hadronic jet with a transverse momentum of p(T) > 30 GeV and a pseudorapidity of vertical bar eta vertical bar < 4.5. After subtracting the background contributions and correcting for detector effects, the jet-inclusive W+W-+ >= 1 jet fiducial cross-section and W+W-+ jets differential cross-sections with respect to several kinematic variables are measured. These measurements include leptonic quantities, such as the lepton transverse momenta and the transverse mass of the W+W- system, as well as jet-related observables such as the leading jet transverse momentum and the jet multiplicity. Limits on anomalous triple-gauge-boson couplings are obtained in a phase space where interference between the Standard Model amplitude and the anomalous amplitude is enhanced.}, organization = {ANPCyT, Argentina}, organization = {YerPhI, Armenia}, organization = {ARC, Australia}, organization = {BMWFW and FWF, Austria}, organization = {ANAS, Azerbaijan}, organization = {SSTC, Belarus}, organization = {CNPq and FAPESP, Brazil}, organization = {NSERC, NRC and CFI, Canada}, organization = {CERN; ANID, Chile}, organization = {CAS, MOST and NSFC, China}, organization = {COLCIENCIAS, Colombia}, organization = {MSMT CR, MPO CR and VSC CR, Czech Republic}, organization = {DNRF and DNSRC, Denmark}, organization = {IN2P3-CNRS and CEA-DRF/IRFU, France}, organization = {SRNSFG, Georgia}, organization = {BMBF, HGF and MPG, Germany}, organization = {GSRT, Greece}, organization = {RGC and Hong Kong SAR, China}, organization = {ISF and Benoziyo Center, Israel}, organization = {INFN, Italy}, organization = {MEXT and JSPS, Japan}, organization = {CNRST, Morocco}, organization = {NWO, Netherlands}, organization = {RCN, Norway}, organization = {MNiSW and NCN, Poland}, organization = {FCT, Portugal}, organization = {MNE/IFA, Romania}, organization = {JINR}, organization = {MES of Russia and NRC KI, Russian Federation}, organization = {MESTD, Serbia}, organization = {MSSR, Slovakia}, organization = {ARRS and MIZŠ, Slovenia}, organization = {DST/NRF, South Africa}, organization = {MICINN, Spain}, organization = {SRC and Wallenberg Foundation, Sweden}, organization = {SERI, SNSF and Cantons of Bern and Geneva, Switzerland}, organization = {MOST, Taiwan}, organization = {TAEK, Turkey}, organization = {STFC, United Kingdom}, organization = {DOE and NSF, United States of America}, organization = {BCKDF, CANARIE, Compute Canada, CRC and IVADO, Canada}, organization = {Beijing Municipal Science & Technology Commission, China}, organization = {COST, ERC, ERDF, Horizon 2020 and Marie Skłodowska-Curie Actions, European Union}, organization = {Investissements d’Avenir Labex, Investissements d’Avenir Idex and ANR, France}, organization = {DFG and AvH Foundation, Germany}, organization = {Herakleitos, Thales and Aristeia programmes co-financed by EU-ESF and the Greek NSRF, Greece}, organization = {BSF-NSF and GIF, Israel}, organization = {La Caixa Banking Foundation, CERCA Programme Generalitat de Catalunya and PROMETEO and GenT Programmes Generalitat Valenciana, Spain}, organization = {Göran Gustafssons Stiftelse, Sweden}, organization = {The Royal Society and Leverhulme Trust, United Kingdom.}, publisher = {Springer}, keywords = {Hadron-Hadron scattering (experiments)}, title = {Measurements of W+W- + >= 1 jet production cross-sections in pp collisions at root s=13 TeV with the ATLAS detector}, doi = {10.1007/JHEP06(2021)003}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Rodríguez Chala, Mikael and Atlas Collaboration}, }
