Inclusive Jet Production in p ¯ p Collisions

We report a new measurement of the pseudorapidity ( η) and transverse-energy ( ET) dependence of the inclusive jet production cross section in p¯p collisions at √s=1.8TeV using 95pb−1 of data collected with the D0 detector at the Fermilab Tevatron. The differential cross section d2σ/(dETdη) 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.
