Measurement of the inclusive jet cross section in p pbar collisions at sqrt(s)=1.96 TeV

Submitted to Phys. Rev. D, See paper for full list authorsWe present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in p pbar collisions at a center-of-mass energy sqrt(s)=1.96 TeV, corresponding to an integrated luminosity of 0.70 fb^(-1). The jet energy calibration and the method used to extract the inclusive jet cross section are described. We discuss the main uncertainties, which are dominated by the jet energy scale uncertainty. The results cover jet transverse momenta from 50 GeV to 600 GeV with jet rapidities in the range -2.4 to 2.4 and are compared to predictions using recent proton parton distribution functions. Studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented

Measurement of the inclusive jet cross section in p(p)over-bar collisions at root s=1.8 TeV

We present results from the measurement of the inclusive jet cross section for jet transverse energies front 40 to 465 GeV in the pseudorapidity range 0.1\<0.7. The results are based on 87 pb(-1) of data collected by the CDF Collaboration at the Fermilab Tevatron collider. The data are consistent with previously published results. The data are also consistent with QCD predictions given the flexibility allowed from current knowledge of the proton parton distributions. We develop a new procedure for ranking the agreement of the parton distributions with data and find that the data are best described by QCD predictions using the parton distribution functions which have a large gluon contribution at high E-T (CTEQ4HJ)
