| 英文摘要 | Various differential cross-sections are measured in top-quark pair (t (t) over bar) events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 tev at the lhc with the atlas detector. these differential cross-sections are presented in a data set corresponding to an integrated luminosity of 4.6 fb(-1). the differential cross-sections are presented in terms of kinematic variables, such as momentum, rapidity and invariant mass, of a top-quark proxy referred to as the pseudo-top-quark as well as the pseudo-top-quark pair system. the dependence of the measurement on theoretical models is minimal. the measurements are performed on tt events in the lepton+jets channel, requiring exactly one charged lepton and at least four jets with at least two of them tagged as originating from a b-quark. the hadronic and leptonic pseudo-top-quarks are defined via the leptonic or hadronic decay mode of the w boson produced by the top-quark decay in events with a single charged lepton. differential cross-section measurements of the pseudo-top-quark variables are compared with several monte carlo models that implement next-to-leading order or leading-order multi-leg matrix-element calculations. |
