The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8TeV, and corresponding to an integrated luminosity of about 20fbinv for each experiment. The measurements used events containing one lepton and having different jet multiplicities in the final state. The results are quoted as fractions of PW bosons with longitudinal (FZ), left-handed (FL), or right-handed (FR) polarizations. The resulting combined measurements of the polarization fracti ... |
