Measurement of the dijet invariant mass cross section in proton anti-proton collisions at √s = 1.96 TeV

The inclusive dijet production double differential cross section as a function of the dijet invariant mass and of the largest absolute rapidity (ymax) of the two jets with the largest transverse momentum in an event is measured in p(bar p) collisions at √s = 1.96 TeV using 0.7 fb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider. The measurement is performed in six rapidity regions up to |y| = 2.4. Next-to-leading order perturbative QCD predictions are found to be in agreement with the data.
