Resumen:
A measurement of the top-antitop charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb 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 based on the identified charged leptons, and , based on the reconstructed tt final state. The asymmetries are measured to be
