abstract = {Various differential cross-sections are measured in top-quark pair (t¯t) events
produced in proton-proton collisions at a centre-of-mass energy of √s = 7TeV 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 t¯t 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.},
