Resumen:
Recent studies have highlighted the potential of jet
substructure techniques to identify the hadronic decays of boosted heavy
particles. These studies all rely upon the assumption that the internal
substructure of jets generated by QCD radiation is well understood. In
this article, this assumption is tested on an inclusive sample of jets
recorded with the ATLAS detector in 2010, which corresponds to 35 pb^-1
of pp collisions delivered by the LHC at sqrt(s) = 7 TeV. In a subsample
of events with single pp collisions, measurementes corrected for
detector efficiency and resolution are presented with full systematic
uncertainties. Jet invariant mass, kt splitting scales and
n-subjettiness variables are presented for anti-kt R = 1.0 jets and
Cambridge-Aachen R = 1.2 jets. Jet invariant-mass spectra for
Cambridge-Aachen R = 1.2 jets after a splitting and filtering procedure
are also presented. Leading-order parton-shower Monte Carlo predictions
for these variables are found to be broadly in agreement with data. The
dependence of mean jet mass on additional pp interactions is also
explored.
