Inclusive Jet Production in pp-bar Collisions

Abstract

We report a new measurement of the pseudorapidity ( η) and transverse-energy ( E(T)) dependence of the inclusive jet production cross section in pp-bar collisions at s√=1.8TeV using 95pb(−1) of data collected with the D0 detector at the Fermilab Tevatron. The differential cross section d(2)σ/(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.
