The W boson helicity fractions from top quark decays in top quark pair 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 F0=0.681 +/- 0.012 (stat) +/- 0.023 (syst), FL=0.323 +/- 0.008 (stat) +/- 0.014 (syst), and FR= -0.004 +/- 0.005 (stat) +/- 0.014 (syst) for the longitudinal, left-, and right-handed components of the helicity, respectively.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.74337.v1/t1","@type":"Dataset","description":"Measurement of the W longitudinal (F0), left- (FL) and righ- (FR) components of the boson helicity fractions from electron+jets final...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.74337.v1/t2","@type":"Dataset","description":"Measurement of the W longitudinal (F0), left- (FL) and righ- (FR) components of the boson helicity fractions from muon+jets final...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.74337.v1/t3","@type":"Dataset","description":"Measurement of the W longitudinal (F0), left- (FL) and righ- (FR) components of the boson helicity fractions from lepton+jets final...","name":"Table 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1466294?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/74337"}],"inLanguage":"en","name":"Measurement of the W boson helicity fractions in the decays of top quark pairs to lepton+jets final states produced in pp collisions at sqrt(s) = 8 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1466294?version=1","version":1}
