Název v původním jazyce

Measurements of top-quark pair differential cross-sections in the lepton+jets channel in pp collisions at s=8 TeV using the ATLAS detector

Popis výsledku v původním jazyce

Measurements of normalized differential cross-sections of top-quark pair production are presented as a function of the top-quark, tt system and event-level kinematic observables in proton–proton collisions at a centre-of-mass energy of s=8TeV . The observables have been chosen to emphasize the tt production process and to be sensitive to effects of initial- and final-state radiation, to the different parton distribution functions, and to non-resonant processes and higher-order corrections. The dataset corresponds to an integrated luminosity of 20.3 fb1 , recorded in 2012 with the ATLAS detector at the CERN Large Hadron Collider. Events are selected in the lepton+jets channel, requiring exactly one charged lepton and at least four jets with at least two of the jets tagged as originating from a b-quark. The measured spectra are corrected for detector effects and are compared to several Monte Carlo simulations. The results are in fair agreement with the predictions over a wide kinematic range.
