Events with exactly one electron, one muon and no hadronic jets are studied. The fiducial region in which the measurements are performed is inspired by searches for the electroweak production of supersymmetric charginos decaying to two-lepton final states. The selected events have moderate values of missing transverse momentum and the `stransverse mass' variable $m_{\\textrm{T2}}$, which is widely used in searches for supersymmetry at the LHC. The ranges of these variables are chosen so that the acceptance is enhanced for direct  $W^{+}W^{-}$ production and suppressed for production via top quarks, which is treated as a background. The fiducial cross-section and particle-level differential cross-sections for six variables are measured and compared with two theoretical SM predictions from perturbative QCD calculations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t1","@type":"Dataset","description":"Signal region detector-level distribution for the observable $|y_{e\\mu}|$.","name":"Figure 1a"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t2","@type":"Dataset","description":"Signal region detector-level distribution for the observable $|\\Delta \\phi(e \\mu)|$.","name":"Figure 1b"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t3","@type":"Dataset","description":"Signal region detector-level distribution for the observable $ \\cos\\theta^{\\ast}$.","name":"Figure 1c"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t4","@type":"Dataset","description":"Signal region detector-level distribution for the observable $p_{\\mathrm{T}}^{\\mathrm{lead}\\, \\ell}$.","name":"Figure 1d"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t5","@type":"Dataset","description":"Signal region detector-level distribution for the observable $m_{e\\mu}$.","name":"Figure 1e"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t6","@type":"Dataset","description":"Signal region detector-level distribution for the observable $p_{\\mathrm{T}}^{e\\mu}$.","name":"Figure 1f"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t7","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $|y_{e\\mu}|$","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t8","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $|y_{e\\mu}|$","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t9","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $|\\Delta \\phi(e \\mu)|$","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t10","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $|\\Delta \\phi(e \\mu)|$","name":"Figure 3d"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t11","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $ \\cos\\theta^{\\ast}$","name":"Figure 3e"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t12","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $ \\cos\\theta^{\\ast}$","name":"Figure 3f"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t13","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $p_{\\mathrm{T}}^{\\mathrm{lead}\\, \\ell}$","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t14","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $p_{\\mathrm{T}}^{\\mathrm{lead}\\, \\ell}$","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t15","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $m_{e\\mu}$","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t16","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $m_{e\\mu}$","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t17","@type":"Dataset","description":"Measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $p_{\\mathrm{T}}^{e\\mu}$","name":"Figure 4e"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t18","@type":"Dataset","description":"Relative systematic uncertainties for the fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for the observable $p_{\\mathrm{T}}^{e\\mu}$","name":"Figure 4f"},{"@id":"https://doi.org/10.17182/hepdata.132115.v1/t19","@type":"Dataset","description":"The statistical correlation coefficients (in percentage) between bins for the measured fiducial differential cross-section of $WW \\rightarrow e^{\\pm}\\nu\\mu^{\\mp}\\nu$ production for...","name":"Aux.
