| dc.description.abstract | A measurement of the top-antitop (tt¯) charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb−1 of LHC pp collisions at a centreof-mass energy of 7 TeV collected by the ATLAS detector. Events with two charged leptons, at least two jets and large missing transverse momentum are selected. Two observables are studied: ACℓℓ based on the identified charged leptons, and Att¯C, based on the reconstructed tt final state. The asymmetries are measured to be. AℓℓC=0.024±0.015(stat.)±0.009(syst.), Att¯C=0.021±0.025(stat.)±0.017(syst.). The measured values are in agreement with the Standard Model predictions. | |
