Dijet azimuthal decorrelations in pp collisions at vs=7TeV

Abstract: Measurements of dijet azimuthal decorrelations in pp collisions at ?s=7?TeV using the CMS detector at the CERN LHC are presented. The analysis is based on an inclusive dijet event sample corresponding to an integrated luminosity of 2.9??pb. The results are compared to predictions from perturbative QCD calculations and various Monte Carlo event generators. The dijet azimuthal distributions are found to be sensitive to initial-state gluon radiation.
