Inclusive jet production in p(p)over-bar collisions

We report a new measurement of the pseudorapidity (eta) and transverse-energy (Er) dependence of the inclusive jet production cross section in p (p) over bar collisions at roots = 1.8 TeV using 95 pb(-1) of data collected with the DO detector at the Fermilab Tevatron. The differential cross section d(2)sigma/(dE(T)d eta) is presented up to \eta\ = 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.
