Measurement of the top quark mass with the template method in the channel using ATLAS data

et al.
Abstract

The top quark mass has been measured using the template method in the $$t\bar{t}\to\mathrm{lepton}+\mathrm{jets}$$ channel based on data recorded in 2011 with the ATLAS detector at the LHC. The data were taken at a proton-proton centre-of-mass energy of $$\sqrt{s}=7\ \mbox{TeV}$$ and correspond to an integrated luminosity of 1.04 fb−1. The analyses in the e+jets and μ+jets decay channels yield consistent results. The top quark mass is measured to be mtop=174.5±0.6stat±2.3syst GeV.
