Description
Properties of jets, including jet multiplicity, are measured with the ATLAS detector in
semileptonic
ttbar events in protonproton
collisions at a centerofmass
energy of 7 TeV. After
background subtraction, corrections are made for detector efficiencies and
resolution effects. The results are compared to Monte Carlo models, consisting of fixedorder
matrix element calculations matched to parton showers.
