Measurement of the top quark mass in the tt dilepton channel from s = 8 TeV ATLAS data
Original language description
The top quark mass is measured in the ttdilepton 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 fb1 . 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=172.990.41 (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 ttdilepton and ttlepton+jets channels results in mtop=172.840.34 (stat)0.61 (syst) GeV , with a total uncertainty of 0.70 GeVnn
