Abstract

Jet physics represents a powerful tool to investigate the properties of quark andgluon interactions. With the advent of LHC, these studies have been possible atan energy never investigated before. In this proceedings we review the main char-acteristics of jets measured by the ATLAS experiment in proton-proton collisionsat center-of-mass energies of 7 and 8 TeV. The experimental results are comparedwith the predictions of the Quantum Chromodymamics, QCD, the standard theory of quark-gluon interactions. A good agreement is found between data and QCD predictions. The jet mesurements provide also a clue in the search for new physics: a few examples of searches for excited quarks and supersymmetric particles are presented.
