  "abstract": "<p>This paper presents a measurement of the inclusive 3-jet production differential cross section at a proton\u2013proton centre-of-mass energy of 7 TeV\u00a0using data corresponding to an integrated luminosity of 5 fb-1 collected with the CMS detector. The analysis is based on the three jets with the highest transverse momenta. The cross section is measured as a function of the invariant mass of the three jets in a range of 445\u20133270 GeV and in two bins of the maximum rapidity of the jets up to a value of 2. A comparison between the measurement and the prediction from perturbative QCD at next-to-leading order is performed. Within uncertainties, data and theory are in agreement. The sensitivity of the observable to the strong coupling constant \u03b1S is studied. A fit to all data points with 3-jet masses larger than 664 GeV gives a value of the strong coupling constant of \u03b1S(MZ)=0.1171\u00b10.0013(exp)-0.0047+0.0073(theo) .</p>",
