Double-differential three-jet production cross-sections are measured in proton–proton collisions at a centre-of-mass energy of s√=7TeV using the ATLAS detector at the large hadron collider. The measurements are presented as a function of the three-jet mass (mjjj) , in bins of the sum of the absolute rapidity separations between the three leading jets (|Y∗|) . Invariant masses extending up to 5 TeV are reached for 8<|Y∗|<10 . These measurements use a sample of data recorded using the ATLAS detector in 2011, which corresponds to an integrated luminosity of 4.51 fb −1 . Jets are identified using the anti- kt algorithm with two different jet radius parameters, R=0.4 and R=0.6 . The dominant uncertainty in these measurements comes from the jet energy scale.
