| Özet |
| The W boson helicity fractions from top quark decays in t t‾ events are measured using data from proton–proton collisions at a centre-of-mass energy of 8 TeV. The data were collected in 2012 with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.8 fb− 1. Events are reconstructed with either one muon or one electron, along with four jets in the final state, with two of the jets being identified as originating from b quarks. The measured helicity fractions from both channels are combined, yielding F 0= 0.681±0.012 (stat)±0.023 (syst), F L= 0.323±0.008 (stat)±0.014 (syst), and F R=− 0.004±0.005 (stat)±0.014 (syst) for the longitudinal, left-, and right-handed components of the helicity, respectively. These measurements of the W boson helicity fractions are the most accurate to date and they agree with the predictions from the standard model. |
