We report on preliminary measurements of the central, [eta][le] 0.5, inclusive jet and dijet cross sections at[radical]s= 1.8 TeV. Two data sets with integrated luminosities of 91 pb[sup[minus]1] and 14 pb[sup[minus]1] were collected at the Fermilab Tevatron p[ovr p] Collider with the D0 detector. The inclusive jet cross section measured with both data sets and reported as a function of transverse jet energy (35 GeV[le] E[sub T][le] 470 GeV) and the dijet cross section measured with the 91 pb[sup[minus]1] data set and reported as a function of dijet mass (200 GeV[le] M[sub JJ][le] 1 TeV) are in excellent agreement with next-to-leading order QCD. 11 refs., 5 figs.
^ 74 GeV and |y| 2.4; the b jets must contain a B hadron. The measurement has significant statistics up to p T ∼ O(TeV). Advanced methods of unfolding are performed to extract the signal. It is found that fixed-order calculations with underlying event describe the measurement well.
The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.
The inclusive b-jet production cross section in pp collisions at a center-of-mass energy of 7 TeV is measured using data collected by the CMS experiment at the LHC. The cross section is presented as a function of the jet transverse momentum in the range 18

Inclusive jet spectra from pp and PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV, collected with the CMS detector at the LHC, are presented. Jets are reconstructed with three different distance parameters for transverse momentum ($p_{\mathrm{T}}$) greater than 70 GeV/$c$ and pseudorapidity $
