We report a new measurement of the pseudorapidity (η) and transverse-energy (ET) dependence of the inclusive jet production cross section in pp̅ collisions at √s = TeV using 95 pb-1 of data collected with the D0 detector at the Fermilab Tevatron. The differential cross section d2σ/(dEr) is presented up to |η| = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD and indicate a preference for certain parton distribution functions.
