A Measurement of the Differential Dijet Mass Cross Section in p-pbar Collisions at sqrt{s}=1.8 TeV

We present a measurement of the cross section for production of two or more jets as a function of dijet mass, based on an integrated luminosity of 86 pb^-1 collected with the Collider Detectorat Fermilab. Our dijet mass spectrumis described within errors by next-to-leading order QCD predictions using CTEQ4HJ partondistributions, and is in good agreement with a similar measurementfrom the D0 experiment.
