| Özet |
| The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb− 1 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 W bosons with longitudinal (F 0), left-handed (F L), or right-handed (F R) polarizations. The resulting combined measurements of the polarization fractions are F 0= 0. 693±0. 014 and F L= 0. 315±0. 011. The fraction F R is calculated from the unitarity constraint to be F R=− 0. 008±0. 007. These results are in agreement with the standard model predictions at next-to-next-to-leading order in perturbative quantum … |
