Jet shapes have been measured in inclusive jet production in proton-proton collisions at {radical}(s)=7 TeV using 3 pb{sup -1} of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-k{sub t} algorithm with transverse momentum 30 GeV<p{sub T}<600 GeV and rapidity in the region |y|<2.8. The data are corrected for detector effects and compared to several leading-order QCD matrix elements plus parton shower Monte Carlo predictions, including different sets of parameters tuned to model fragmentation processes and underlying event contributions in the final state. 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. In particular, the data show sensitivity to the details of the parton shower, fragmentation, and underlying event models in the Monte Carlo generators. For an appropriate choice of the parameters used in these models, the data are well described.
