Top-quark mass measurement in the all-hadronic tt decay channel at √s = 8 TeV with the ATLAS detector Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration, / Hadron-Hadron scattering (experiments) Top physics The top-quark mass is measured in the all-hadronic top-antitop quark decay channel using proton-proton collisions at a centre-of-mass energy of √s = 8TeV with the ATLAS detector at the CERN Large Hadron Collider. The data set used in the analysis corresponds to an integrated luminosity of 20.2 fb-1. The large multi-jet background is modelled using a data-driven method. The top-quark mass is obtained from template fits to the ratio of the three-jet to the dijet mass. The three-jet mass is obtained from the three jets assigned to the top quark decay. From these three jets the dijet mass is obtained using the two jets assigned to the W boson decay. The top-quark mass is measured to be 173.72 ± 0:55 (stat.) ± 1.01 (syst.) GeV. 2024-10-11T11:42:51Z 2024-10-11T11:42:51Z 2017-09-25 journal article The ATLAS collaboration., Aaboud, M., Aad, G. et al.
