Názov: Priame meranie rozpadovej šírky top kvarku s využitím dát z experimentu ATLAS pri ťažiskovej energií 8 TeV

Abstrakt: 
The data sample is collected by the ATLAS detector at the LHC in proton-proton collisions at a centre-of-mass energy of 8 TeV and corresponds to an integrated luminosity of 20.2 inverse femtobarns. The decay width of the top quark is measured using a template fit to distributions of kinematic observables associated with the hadronically and semileptonically decaying top quarks. The result, top-quark decay width = 1.76 ± 0.33 (stat.) + 0.79 - 0.68 (syst.) GeV,  is consistent with the prediction of the Standard Model.
