Abstract We present preliminary results on dijet production in p-pbar collisions at √s=1.96 TeV using data collected by the CDF Collaboration in Fermilab Tevatron Run II corresponding to an integrated luminosity of 1.13 fb^-1. Jets are reconstructed using the Midpoint algorithm with R=0.7. The differential dijet mass cross section is measured for dijet events with the dijet mass above 180 GeV/c² and |y^jet1,2|<1.0. The data is compared to the next-to-leading order perturbative QCD predictions.
