The transverse momentum (pT) dependence of azimuthal decorrelations in dijet events is studied with data collected, at an integrated luminosity of [special characters omitted] dt = (36 ± 4) pb−1, from collisions between protons at a center of mass energy of [special characters omitted] = 7 TeV using the ATLAS detector at the Large Hadron Collider. The results of the analysis of jets in a central rapidity of |y| < 0.8 and pT in the range 60 GeV < pT < 1200 GeV are presented. A new observable RΔ&phis;, defined as the fraction of the total dijet cross section corresponding to a particular range of opening angles between the two jets with the highest pT, is measured as a differential quantity in the pT of the jet with highest pT. The results of the analysis are compared with good agreement to next-to-leading order perturbative QCD calculations as well as the predictions from different Monte Carlo generators including PYTHIA and ALPGEN.
