We report a new measurement of the pseudorapidity ({eta}) and transverse-energy (E{sub T}) dependence of the inclusive jet production cross section in p{bar p} collisions at {radical}s = 1:8 TeV using 95 pb{sup {minus}1} of data collected with the D0 detector at the Fermilab Tevatron. The differential cross section d{sup 2}{sigma}/(dE{sub T}d{eta}) is presented up to {vert_bar}{eta}{vert_bar} = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD, indicate a preference for certain parton distribution functions, and provide the world's best constraint on the gluon distribution at high parton momentum fraction x.
