The first measurements of production cross sections of polarized same-sign W±W± boson pairs in
proton-proton collisions are reported. 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 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 W±W± 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 W±W± boson pairs. The electroweak production of same-sign W±W±
boson pairs with at least one of the W bosons longitudinally polarized is measured with an observed
(expected) significance of 2.3 (3.1) standard deviations
