Abstract (data abstract)
CERN-LHC. CMS. Azimuthal correlations between the two jets with the largest transverse momenta $p_{T}$ in inclusive 2-, 3-, and 4-jet events are presented for several regions of the leading jet $p_{T}$ up to 4 TeV. For 3- and 4-jet scenarios, measurements of the minimum azimuthal angles between any two of the three or four leading $p_{T}$ jets are also presented. Jets are reconstructed using the infrared- and collinear-safe anti-$k_{T}$ clustering algorithm with a distance parameter $R=0.4$.
