Measurement of the Dijet Mass Spectrum at $\sqrt{s}$=1.96 TeV in the D0 experiment

We present the differential dijet mass cross section measurement at a center of mass energy of 1.96 TeV in six rapidity regions using the D0 detector. This measurement utilizes 0.7 fb$^{-1}$ of integrated luminosity collected in proton-antiproton collisions during Run IIa of the Fermilab Tevatron. We correct the data back to particle level and compare it to parton-level theory to which fragmentation and underlying event corrections have been added.
