Abstract

Correlations in the azimuthal angle between the two largest transverse momentum jets have been measured using the D∅ detector in pp¯ collisions at a center-of-mass energy √s=1.96 TeV. The analysis is based on an inclusive dijet event sample in the central rapidity region corresponding to an integrated luminosity of 150 pb. Azimuthal correlations are stronger at larger transverse momenta. These are well described in perturbative QCD at next-to-leading order in the strong coupling constant, except at large azimuthal differences where contributions with low transverse momentum are significant.
