Physics Letters B 761: 350-371. doi:10.1016/j.physletb.2016.08.0420370-2693http://nrs.harvard.edu/urn-3:HUL.InstRepos:29362060The top quark mass is measured in the tt¯ → 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 = 8 TeV 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 tt¯ → dilepton and tt¯ → lepton+jets channels results in mtop = 172.84 ±0.34 (stat) ±0.61 (syst) GeV, with a total uncertainty of 0.70 GeV.en-USJournal Article2016-11-0710.1016/j.physletb.2016.08.042
