Resumen:
A measurement of jet shapes in top-quark pair events using 1.8 fb−1 of s = 7 TeV pp collisiondata recorded by the ATLAS detector at the LHC is presented. Samples of top-quark pair events areselected in both the single-lepton and dilepton final states. The differential and integrated shapes ofthe jets initiated by bottom-quarks from the top-quark decays are compared with those of the jets ̄originated by light-quarks from the hadronic W -boson decays W → qq in the single-lepton channel.The light-quark jets are found to have a narrower distribution of the momentum flow inside the jet areathan b-quark jets.
