Measurement of the Inclusive Jet Cross Section in pp Collisions at sqrt(s) = 7 TeV

TL;DR

This paper reports the measurement of the inclusive jet cross section in proton-proton collisions at 7 TeV using CMS data, covering a wide pT range and confirming agreement with QCD predictions at high energies.

Contribution

First measurement of the inclusive jet cross section at 7 TeV covering jet pT up to 1100 GeV with CMS at the LHC.

Findings

Measured cross section extends to highest jet pT observed.

Results agree with next-to-leading-order QCD predictions.

Provides data for testing QCD at unprecedented energies.

Abstract

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.
