Measurement of the charge asymmetry in dileptonic decays of top quark pairs in pp collisions at s = 7 TeV using the ATLAS detector
Original language description
A measurement of the top-antitop (tt) charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb1 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 based on the identified charged leptons, and AttC , based on the reconstructed tt final state. The asymmetries are measured to be A??C=0.0240.015(stat.)0.009(syst.), AttC=0.0210.025(stat.)0.017(syst.).
