Abstract
The D0 Collaboration has measured the inclusive jet cross section in p̅p collisions at √s=630 GeV. The results for pseudorapidities ||(η)<0.5 are combined with our previous results at √s=1800 GeV to form a ratio of cross sections with smaller uncertainties than either individual measurement. Next-to-leading-order QCD predictions show excellent agreement with the measurement at 630 GeV; agreement is also satisfactory for the ratio. Specifically, despite a 10% to 15% difference in the absolute magnitude, the dependence of the ratio on jet transverse momentum is very similar for data and theory.
