Query: Measurement of event shapes at large momentum transfer with the ATLAS
  detector in pp collisions at sqrt(s) = 7 TeV   A measurement of event shape variables is presented for large momentum
transfer proton-proton collisions using the ATLAS detector at the Large Hadron
Collider. Six event shape variables calculated using hadronic jets are studied
in inclusive multi-jet events in 35 pb^-1 of integrated luminosity at a
center-of-mass energy of sqrt(s) = 7 TeV. These measurements are compared to
predictions by three Monte Carlo event generators containing
leading-logarithmic parton showers matched to leading order matrix elements for
2 to 2 and 2 to n (n=2,...6) scattering. Measurements of the third-jet
resolution parameter, aplanarity, thrust, sphericity, and transverse sphericity
are generally well described. The mean value of each event shape variable is
evaluated as a function of the average momentum of the two leading jets pT1 and
pT2, with a mean pT approaching 1 TeV.
