Abstract:
A measurement of jet shapes in top-quark pair
events using 1.8 fb−1 of √s = 7 TeV pp collision data
recorded by the ATLAS detector at the LHC is presented.
Samples of top-quark pair events are selected in both the
single-lepton and dilepton final states. The differential and
integrated shapes of the 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 →q ¯q in the single-lepton channel. The light-quark
jets are found to have a narrower distribution of the momentum
flow inside the jet area than b-quark jets.
