520 _ _ |a This paper presents a direct measurement of the decay width of the top quark using $t\bar{t}$ events in the lepton+jets final state. The data sample was 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 fb$^{-1}$. 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, $\Gamma_t = 1.76 \pm 0.33 (\rm{stat.}) ^{+0.79}_{-0.68} (\rm{syst.}) \rm{GeV}$ for a top-quark mass of 172.5 GeV, is consistent with the prediction of the Standard Model.
