Measurement of the W-boson helicity in top-quark decays from t[overline t] production in lepton+jets events in pp collisions at √s =7 TeV

Measurement of the W-boson helicity in top-quark decays from t[overline t] production in lepton+jets events in pp collisions at √s =7 TeV

The W-boson helicity fractions in top-quark decays are measured with tt̄ events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7TeV, collected in 2011 with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 5.0 fb [su...
