Measurement of jet shapes in top-quark pair events at √ s = 7 TeV using the ATLAS detector

Mostrar todas las versiones(2)

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 th...
