Two jet production and triple differential cross sections

Large samples of data with jets at high pseudorapidities have been collected at the Fermilab Tevatron pp̄ collider at √s=1.8 TeV. Both the DO/ and CDF experiments have used the dijet cross sections, d³σ/dE_Tdη₁dη₂, to make detailed tests of perturbative QCD. These data sets will eventually place constraints on the gluon distribution functions. Results presented here are from data taken during 1992–1993.
