The measurements are based on a data sample collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $137~\\mathrm{fb}^{-1}$. Events are selected by requiring exactly two same-sign leptons, electrons or muons, moderate missing transverse momentum, and two jets with a large rapidity separation and a large dijet mass to enhance the contribution of same-sign $\\mathrm{W}^{\\pm}\\mathrm{W^{\\pm}}$ scattering events. An observed (expected) 95\\% confidence level upper limit  of 1.17 (0.88) fb is set on the production cross section for longitudinally polarized same-sign $\\mathrm{W}^{\\pm}\\mathrm{W^{\\pm}}$ boson pairs. The electroweak production of same-sign $\\mathrm{W}^{\\pm}\\mathrm{W^{\\pm}}$ boson pairs with at least one of the $\\mathrm{W}$ bosons longitudinally polarized is measured with an observed (expected) significance of 2.3 (3.1) standard deviations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.96027.v1/t1","@type":"Dataset","description":"Systematic uncertainties of the $\\mathrm{W}^\\pm_{\\mathrm{L}}\\mathrm{W}^\\pm_{\\mathrm{L}}$ and $\\mathrm{W}^\\pm_{\\mathrm{X}}\\mathrm{W}^\\pm_{\\mathrm{T}}$, and $\\mathrm{W}^\\pm_{\\mathrm{L}}\\mathrm{W}^\\pm_{\\mathrm{X}}$ and $\\mathrm{W}^\\pm_{\\mathrm{T}}\\mathrm{W}^\\pm_{\\mathrm{T}}$ cross section measurements in units of percent.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.96027.v1/t2","@type":"Dataset","description":"Expected yields from various SM processes and observed data events in WW SR.
