Title: | Direct top-quark decay width measurement in the tt¯ lepton+jets channel at √s=8TeV with the ATLAS experiment | Authors: | Santos, S. P. Amor dos Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2018 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 78 | Issue: | 2 | Abstract: | This paper presents a direct measurement of the decay width of the top quark using t ¯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, t = 1.76 ± 0.33 (stat.) +0.79 −0.68 (syst.) GeV for a top-quark mass of 172.5 GeV, is consistent with the prediction of the Standard Model. | URI: | https://hdl.handle.net/10316/107583 | DOI: | 10.1140/epjc/s10052-018-5595-5 | Rights: | openAccess |
