Measurement of the Top Quark Mass in Dileptonic Top Quark Pair Decays with $\sqrt{s}=7$ TeV ATLAS Data
This note presents a measurement of the top quark mass in dileptonic top quark pair decays using 4.7 fb−1 of $\sqrt{s} = 7$ TeV pp collision data recorded by the ATLAS experiment at the Large Hadron Collider in 2011. This event topology is characterised by the presence of two charged leptons, at lea...

| description | This note presents a measurement of the top quark mass in dileptonic top quark pair decays using 4.7 fb−1 of $\sqrt{s} = 7$ TeV pp collision data recorded by the ATLAS experiment at the Large Hadron Collider in 2011. This event topology is characterised by the presence of two charged leptons, at least two neutrinos and several jets, two of which originate from bottom quarks. Using the template method and the mlb observable, defined as the average invariant mass of the two lepton plus b-jet pairs in each event, the top quark mass is measured to be 173.09 ±0.64 (stat) ±1.50 (syst) GeV. |
