dc.abstract.en A measurement of the top-antitop \left ( t\bar{t} \right ) 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: A_{C}^{\ell \ell} based on the identified charged leptons, and A_{C}^{t\bar{t}}, based on the reconstructed tt final state. The asymmetries are measured to be A_{C}^{\ell \ell} =0.024\pm 0.015\left ( stat. \right )\pm 0.009\left ( syst. \right ), A_{C}^{t\bar{t}} =0.021\pm 0.025\left ( stat. \right )\pm 0.017\left ( syst. \right ). The measured values are in agreement with the Standard Model predictions. pl
