Query: Performance of jet substructure techniques for large-R jets in
  proton-proton collisions at sqrt(s) = 7 TeV using the ATLAS detector   This paper presents the application of a variety of techniques to study jet
substructure. The performance of various modified jet algorithms, or jet
grooming techniques, for several jet types and event topologies is investigated
for jets with transverse momentum larger than 300 GeV. Properties of jets
subjected to the mass-drop filtering, trimming, and pruning algorithms are
found to have reduced sensitivity to multiple proton-proton interactions, are
more stable at high luminosity and improve the physics potential of searches
for heavy boosted objects. Studies of the expected discrimination power of jet
mass and jet substructure observables in searches for new physics are also
presented. Event samples enriched in boosted W and Z bosons and top-quark pairs
are used to study both the individual jet invariant mass scales and the
efficacy of algorithms to tag boosted hadronic objects. The analyses presented
use the full 2011 ATLAS dataset, corresponding to an integrated luminosity of
4.7 +/- 0.1 /fb from proton-proton collisions produced by the Large Hadron
Collider at a center-of-mass energy of sqrt(s) = 7 TeV.
