Abstract (data abstract)
CERN-LHC. Study of inclusive multi-jet production in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample was collected from April to August 2010 and has a total integrated luminosity of 2.4 pb^{-1} with a 3.4% uncertainty. Jets are identified using the anti-KT algorithm with results given for both R=0.4 and R=0.6. Jet multiplicities and differential cross sections are presented together with various ratios. The data are compared to Monte-Carlo predictions. In the tables where two systematic (sys) errors are shown, the first is the uncertainty on the jet energy scale and the second is the unfolding uncertainty. Note added (26 JUN 2014): The cross section values reported in Tables 1, 3-9 below should be multiplied by a factor of 1.0187 to take into account the updated value of the integrated luminosity for the ATLAS 2010 data taking period. The uncertainty on the global normalisation ("Lumi") increases slightly from 3.4% to 3.5%. See Eur.Phys.J. C73 (2013) 2518 for more details.
