dc.description.abstract The top quark mass is measured in the t¯t → dilepton channel (lepton = e, μ) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of √s = 8TeV and correspond to an integrated luminosity of about 20.2 fb-1. Exploiting the template method, and using the distribution of invariant masses of lepton–b-jet pairs, the top quark mass is measured to be mtop = 172.99 ±0.41 (stat) ±0.74 (syst) GeV, with a total uncertainty of 0.84 GeV. Finally, a combination with previous ATLAS mtop measurements from s = 7 TeV data in the t¯t → dilepton and t¯t → lepton + jets channels results in mtop = 172.84 ± 0.34 (stat) ±0.61 (syst) GeV, with a total uncertainty of 0.70 GeV. en
