Title: Jet Production at High Energy

Session: Either New Developments in QCD or Origins of Flavor Physics/Fermion masses


We report  preliminary measurements of inclusive 
jet and di-jet production cross sections at a center of mass energy of 1.8 TeV.
The  data set with integrated luminosity of 91 pb-1  
was collected at the Fermilab Tevatron proton-antiproton Collider with the 
DZERO detector. The inclusive cross section, reported as a function of
transverse jet energy between 35 and 470 GeV and in the central unit of 
pseudorapidity, is in excellent agreement with next-to-leading order QCD.
The di-jet mass distribution and the di-jet angular distributions allow stringent 
limits to be set on the production of new particles and on quark substructure.
