Abstract
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 s = 7 TeV.In a subsample of events with single pp collisions, measurements corrected for detector efficiency and resolution are presented with full systematic uncertainties.Jet invariant mass, k t splitting scales and N -subjettiness variables are presented for anti-k t 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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
