  "description": "<p>A measurement of the mass difference between top and anti-top quarks is presented. In a 4.7 fb\u22121 data sample of proton\u2013proton collisions at s=7 TeV recorded with the ATLAS detector at the LHC, events consistent with tt\u00af production and decay into a single charged lepton final state are reconstructed. For each event, the mass difference between the top and anti-top quark candidate is calculated. A two b -tag requirement is used in order to reduce the background contribution. A maximum likelihood fit to these per-event mass differences yields \u0394m\u2261mt\u2212mt\u00af=0.67\u00b10.61(stat)\u00b10.41(syst) GeV , consistent with CPT invariance.</p>",
