Resumo
Correlations in the azimuthal angle between the two largest transverse momentum jets have been measured using the D0 detector in pp̄ collisions at a center-of-mass energy s=1.96TeV. The analysis is based on an inclusive dijet event sample in the central rapidity region corresponding to an integrated luminosity of 150pb-1. 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. © 2005 The American Physical Society.
