Study of jet shapes in inclusive jet production in pp collisions at √s=7TeV using the ATLAS detector

Jet shapes have been measured in inclusive jet production in proton-proton collisions at √s=7TeV using 3pb - 1 of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-k t algorithm with transverse momentum 30GeV<p T <600GeV and rapidity in the region...

The measured jets become narrower with increasing jet transverse momentum and the jet shapes present a moderate jet rapidity dependence. Within QCD, the data test a variety of perturbative and nonperturbative effects.
