QCD and diffraction results from DØ Run II

This paper presents recent results in QCD and diffraction physics obtained by the DØ experiment at the Fermilab Tevatron pp¯ collider at s=1.96 TeV. The data used correspond to an integrated luminosity up to 150 pb−1. The different measurements are jet inclusive and dijet cross sections, dijet azimuthal decorrelation, diffractively produced Z bosons and elastic scattering study.
