Abstract
Measurements are presented of the properties of high transverse momentum
jets, produced in proton-proton collisions at a center-of-mass energy of
sqrt(s) = 7 TeV. The data correspond to an integrated luminosity of 35 pb^-1
and were collected with the ATLAS detector in 2010. Jet mass, width,
eccentricity, planar flow and angularity are measured for jets reconstructed
using the anti-kt algorithm with distance parameters R = 0.6 and 1.0, with
transverse momentum pT > 300 GeV and pseudorapidity |eta| < 2. The measurements
are compared to the expectations of Monte Carlo generators that match
leading-logarithmic parton showers to leading-order, or next-to-leading-order,
matrix elements. The generators describe the general features of the jets,
although discrepancies are observed in some distributions.
