Jet results from ATLAS

Several jet observables have been measured in proton-proton collisions at centre-of-mass energy of 7 TeV using the ATLAS detector. Differential inclusive single jet cross sections and dijet cross sections have been measured in the large kinematic region with rapidity up to 4.4 and jet transverse momentum up to 1.4TeV. The results are compared with various predictions calculated by next-to-leading order QCD with several parton distribution functions. Also, inclusive and dijet cross sections of b-jets have been measured and the results are compared with next-to-leading order QCD calculation. Measurements of multi-jet cross sections, azimuthal decorrelation of dijets, dijets with large rapidity gaps and jet shapes are also presented.
