The cross section is measured in a fiducial phase-space region defined by the presence of exactly one electron and one muon, missing transverse momentum and exactly one jet with a transverse momentum above 25 GeV and a pseudorapidity of $|\\eta|<4.5$. The leptons are required to have opposite electric charge and to pass transverse momentum and pseudorapidity requirements. The fiducial cross section is found to be $\\sigma^{\\mathrm{fid,1\\textrm{-}jet}}_{WW}=136\\pm6($stat$)\\pm14($syst$)\\pm3($lumi$)$ fb. In combination with a previous measurement restricted to leptonic final states with no associated jets, the fiducial cross section of $WW$ production with zero or one jet is measured to be $\\sigma^{\\mathrm{fid,}\\leq\\mathrm{1\\textrm{-}jet}}_{WW}=511\\pm9($stat$)\\pm26($syst$)\\pm10($lumi$)$ fb. The ratio of fiducial cross sections in final states with one and zero jets is determined to be $0.36\\pm0.05$. Finally, a total cross section extrapolated from the fiducial measurement of $WW$ production with zero or one associated jet is reported. The measurements are compared to theoretical predictions and found in good agreement.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79950.v1/t1","@type":"Dataset","description":"Measured production cross section of WW production in the fiducial region in case one W boson decays into a prompt...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.79950.v1/t2","@type":"Dataset","description":"Measured production cross section of WW production in the fiducial region in case one W boson decays into a prompt...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.79950.v1/t3","@type":"Dataset","description":"Measured ratio of the production cross section of WW production with one associated jet to the production cross section of...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.79950.v1/t4","@type":"Dataset","description":"Measured total production cross sections of WW production in the total phase space.
