Sumario: | Jet substructure reconstruction techniques are applied in the context of the reconstruction of heavy boosted particles, with a particular emphasis on searches for new physics, and in other analyses sensitive to the origin of the jets. The ATLAS experiment at the LHC conducts extensive performance evaluations for a series of substructure techniques using proton-proton collision data taken in 2011 at $\sqrt{s}=7$ TeV. Selected results for various observables and their sensitivity to experimental conditions like pile-up are presented, together with comparisons to Monte Carlo simulations. It is found that most of the considered jet substructure related mass, distance and splitting scale measures can be understood with precisions of better than 10%. |
