Abstract:
Measurements are presented of the properties of high transverse momentum jets, produced in protonproton
collisions at a center-of-mass energy of pffisffiffi ¼ 7 TeV. The data correspond to an integrated
luminosity of 35 pb1 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 ¼ 0:6 and 1.0, with transverse momentum pT > 300 GeV and pseudorapidity jj < 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.
