Description

We present measurements sensitive to QCD multijet production using data from proton-proton collisions at sqrt(s) = 7 TeV collected with the CMS detector at the CERN LHC. The hadronic event shapes, the dijet azimuthal decorrelation and the ratio of the 3 jet to 2 jet production cross-sections confront the QCD multijet dynamics at a previously unexplored kinematic regime. The data are compared to various QCD Monte Carlo models.
