Study of Inclusive Jet Production and Jet Shapes in proton-proton collisions at $\sqrt$s = 7 TeV using the ATLAS Detector

Abstract

This Thesis presents the measurement of the inclusive jet cross section using the full 2010 data set, corresponding to 37 pb^{-1} collected by ATLAS. Jets with p_{T} > 20 GeV and |y| < 4.4 are considered in this analysis. The measurement of the jet shapes using the first 3 pb^{-1} is also presented, for jets with p_{T} > 30 GeV and |y| < 2.8. Both measurements are unfolded back to the particle level. Results are compared to theoretical predictions, showing the potential of the measurements to test QCD, and its importance in the search for new physics.
