Phys. J. C PY 2011 BP 1763 EP 27pp VL 71 IS 11 DI 10.1140/epjc/s10052-011-1763-6 LA English AB Inclusive multi-jet production is studied in proton-proton collisions at a center-of-mass energy of 7 TeV, using the ATLAS detector. The data sample corresponds to an integrated luminosity of 2.4 pb(-1). Results on multi-jet cross sections are presented and compared to both leading-order plus parton-shower Monte Carlo predictions and to next-to-leading-order QCD calculations. ER
