Jet Production in proton-proton collisions at sqrt(s) =7 TeV with the ATLAS experiment

Abstract

We report on the first measurements done with the ATLAS experiment of the characteristics of energetic jets produced in proton-proton collisions at the center of mass energy of 7 TeV. Jets are reconstructed using the anti-kt clustering algorithm with distance parameter R=0.6. The kinematic region investigated in this paper corresponds to jets with transverse momentum p_T>30$GeV and rapidity |y_jet |<2.8. A critical understanding of the jet production is obtained by comparing the data to predictions based on leading-order QCD matrix elements plus parton shower Monte Carlo simulated events. The results shown are obtained on a data sample corresponding to about 1 nb**-1 of integrated luminosity delivered by the Large Hadron Collider.
